Labor Day Cucumber Tomato Salad: Cheap & Easy

Last year, I made the classic mistake. You know the one. You spend hours marinating chicken, firing up the grill, and sweating over coals, only to realize halfway through prep that you have absolutely nothing green to serve alongside it. My husband looked at me like I’d just told him we were out of coffee. “What about sides?” he asked, eyeing the empty counter where a bowl of salad should have been.

I panicked. I ran to the store, bought a sad bag of pre-washed spinach that was already wilting, and tried to dress it up with croutons. It was… okay. But it didn’t feel right. It felt like an afterthought. And honestly? It was.

This year, I’m doing it differently. I’m making my Labor Day Cucumber Tomato Salad with Feta and Red Onion. It’s the kind of dish that takes ten minutes to throw together but looks like you spent an hour plating it. It’s cheap, it’s refreshing, and it’s the perfect counterpoint to all that heavy BBQ food. Seriously, when you’re eating smoky ribs or charred chicken skewers, you don’t want another heavy potato salad. You want something crisp, cool, and bright. This salad delivers exactly that.

I’ve tested this recipe about a dozen times this summer alone. I’ve made it for casual Tuesday dinners, for potlucks where I didn’t want to bring anything complicated, and yes, for last-minute guests who showed up unannounced. It’s my go-to because it requires zero cooking, uses ingredients I already have in the fridge, and stretches incredibly far. If you’re feeding a crowd on a budget, this is your new best friend.

Why You’ll Love This Cucumber Tomato Salad

Let’s be real: summer parties are exhausting. Between managing the grill, keeping drinks cold, and trying to socialize while your kids run around, you don’t have time for complicated cooking. This salad is your secret weapon for looking like a hosting pro without the stress.

Stupid Simple — There is no cooking. No chopping finesse required. I just chop things into bite-sized pieces and toss them. If you can peel a banana, you can make this. I’ve let my kids help with the tossing, and they actually eat the vegetables when they’re part of the “mixing team.”

Lightning Fast — From fridge to table in 10 minutes. Seriously. I chopped the cucumbers and tomatoes while the BBQ chicken skewers were resting. It’s the fastest side dish I own. Perfect for when the grill is full and you realize you forgot dessert.

Super Budget-Friendly — This is the part I love most. Cucumbers and tomatoes are cheap in the summer. Feta is pricey, but you only need a little bit for flavor. I can make this for under $5, which feeds 6-8 people easily. That’s less than a dollar a serving. Compare that to buying a fancy garden salad at the grocery store for $8, and this is a no-brainer.

Makes-Head Friendly — Unlike leafy greens that wilt in the fridge, cucumbers and tomatoes hold up beautifully. I actually prefer making this a few hours ahead. The flavors meld together, the onions soften just a bit, and it tastes better the longer it sits. I’ll make this in the morning before the party starts, and it stays crisp in the fridge until we’re ready to eat.

Perfect Balance — Summer BBQ is heavy. Think rich meats, cheesy casseroles, and starchy sides. This salad is the palate cleanser we all need. The acidity from the vinegar and lemon cuts through the grease, and the crunch is just satisfying. It’s the kind of side dish that people actually fight over.

Ingredients You’ll Need

Here’s the best part: this list is short. You probably have most of this already. I’m not asking you to buy exotic ingredients or special equipment. Just good, fresh produce and a few pantry staples.

For the Salad Base

English Cucumbers (2 large, chopped / about 600g) — I specifically use English cucumbers (also called hothouse or seedless) because they have thinner skins and fewer seeds. Regular slicing cucumbers work too, but you’ll need to peel them and scoop out the watery seeds, or the salad gets soggy. If you use regular cucumbers, peel them first. English cucumbers don’t need peeling.

Ripe Tomatoes (1.5 pounds / about 700g) — Use whatever is on sale. Beefsteak tomatoes are great for chunky salads, but cherry tomatoes halved are faster and sweeter. If it’s peak tomato season, buy the ugly ones—they taste the best and cost less. I like a mix of red and yellow for color, but red is fine.

Red Onion (1 medium, thinly sliced / about 150g) — This adds that necessary bite. Red onion is milder than yellow onion and looks pretty. If you’re sensitive to raw onion, soak the slices in ice water for 10 minutes before adding them. It takes the sharpness away.

For the Feta & Dressing

Feta Cheese (6 ounces / 170g, crumbled) — Don’t buy the pre-crumbled stuff in the plastic tub. It’s coated in potato starch so it doesn’t clump, which means it doesn’t melt or distribute well. Buy a block and crumble it yourself with your fingers. It’s cheaper and tastes so much better. I use a full block because the saltiness is key.

Olive Oil (¼ cup / 60ml) — Use extra virgin. This is one of the few times I’m picky about oil. It’s the main fat source, so it should taste good. If you’re out, neutral oil works, but the flavor won’t be as rich.

Red Wine Vinegar (2 tablespoons / 30ml) — This gives it that tangy kick. Apple cider vinegar works too, but red wine vinegar has a sharper bite that pairs well with feta. Balsamic is too sweet for this specific profile.

Fresh Lemon Juice (1 tablespoon / 15ml) — Just one lemon. It brightens everything up and adds freshness that vinegar alone can’t do. Squeeze it yourself. Bottled lemon juice tastes flat.

Dried Oregano (1 teaspoon) — This is non-negotiable. It’s what makes it taste like a Greek salad. If you don’t have oregano, use dried basil, but oregano is the classic choice. Fresh oregano works but add it at the end so it doesn’t wilt.

Kalamata Olives (½ cup, pitted / optional) — I love olives in this, but they’re optional. If you’re feeding picky eaters or kids, skip them. If you’re serving adults, toss them in. They add a salty, briny depth that’s amazing.

Seasoning

Sea Salt (½ teaspoon) — Taste before adding. Feta is salty, so start low. You can always add more.

Black Pepper (½ teaspoon, freshly cracked) — Freshly cracked makes a difference. Pre-ground pepper is dusty and weak.

Equipment Needed

You don’t need fancy gadgets for this. Here’s what I actually use.

Large Mixing Bowl — I use a 5-quart stainless steel bowl. It needs to be big enough to toss everything without spilling. If you don’t have a big bowl, use your biggest salad spinner bowl or even a clean large pot.

Sharp Chef’s Knife — For chopping cucumbers and tomatoes. A dull knife will crush the tomatoes and make a mess. Keep it sharp. I learned this the hard way with a bruised tomato disaster.

Cutting Board — Any size works. I use a large plastic one for easy cleanup.

Whisk or Fork — To mix the dressing. A small whisk is nice, but a fork works perfectly fine. Dollar store versions are fine.

Serving Spoon — A large wooden spoon or salad server. I like wooden because it doesn’t scratch the bowl.

How to Make It: Step-by-Step

Alright, let’s make this! It’s so simple I almost feel like I’m cheating. But that’s the beauty of it.

Step 1: Prep Your Vegetables (5 minutes)

Wash your cucumbers and tomatoes. Pat them dry. If you’re using regular cucumbers, peel them. If you’re using English cucumbers, leave the skin on—it adds color and crunch. Chop the cucumbers into half-moon slices or bite-sized chunks. I prefer half-moons because they’re easier to eat with a fork. Chop the tomatoes into similar-sized chunks. You want everything to be roughly the same size so every bite has a mix of flavors.

Step 2: Slice the Onion

Peel the red onion and slice it into thin half-rings. If you’re worried about the onion being too strong, put the slices in a bowl of ice water for 10 minutes. Drain and pat dry. This step is optional but recommended if you’re serving kids or people who hate raw onion bite.

Step 3: Make the Dressing

In a small bowl or jar, whisk together the olive oil, red wine vinegar, lemon juice, oregano, salt, and pepper. Whisk until it’s emulsified (it should look creamy and mixed, not separated). Taste it. If it needs more acid, add a splash more lemon. If it needs more salt, add a pinch. You want it to taste slightly too salty on its own, because the vegetables will dilute it.

Step 4: Combine the Salad

Put the chopped cucumbers, tomatoes, and onions in your large mixing bowl. Pour the dressing over the top. Toss gently but thoroughly. You want every piece coated. Be careful not to mash the tomatoes. Use two large spoons or clean hands to toss.

Step 5: Add the Feta and Olives

Crumble the feta cheese over the top. If you’re using olives, add them now. Toss one more time, gently folding the cheese in so it distributes evenly. Don’t stir so hard that the cheese turns into paste. You want chunks of feta in every bite.

Step 6: Chill and Serve

Cover the bowl with plastic wrap or a lid and refrigerate for at least 30 minutes, or up to 4 hours. This lets the flavors meld. When you’re ready to serve, give it a final toss. Taste and adjust salt if needed. Serve cold.

Total Time: 10 minutes active, plus chilling time.

Expert Tips & Tricks

Here’s everything I’ve learned from making this dozens of times. These tips will save you from my mistakes.

Don’t Skip the Chilling Time

I know you want to eat it now. But let it sit. The salt from the feta and the vinegar draw out some moisture from the vegetables, creating a natural dressing. It tastes bland if you serve it immediately. 30 minutes is the minimum. Overnight is best.

Drain Excess Liquid Before Serving

After chilling, you might see a little liquid at the bottom of the bowl. This is normal. If you’re serving it at a party where people might let it sit out, drain off that excess liquid before serving. It keeps the salad from getting watery.

Use Good Feta

I can’t stress this enough. Cheap feta tastes salty and artificial. Spend the extra dollar on a block of real feta from the cheese counter. It’s creamy, tangy, and crumbles beautifully. My husband can tell the difference. He’ll complain if I use the cheap stuff.

Balance the Ratios

If you’re not a fan of onion, reduce it to half. If you love feta, double it. This recipe is flexible. I usually aim for a 2:1 ratio of cucumber to tomato, but it depends on what’s on sale.

Make-Ahead Strategy

Chop everything the night before. Store the veggies in separate containers in the fridge. Mix the dressing in a jar. In the morning, combine everything. It saves so much stress on the day of the party. I do this for every summer gathering.

Variations & Substitutions

Once you’ve nailed the basic version, here’s how you can mix it up. I’ve tried all of these.

Mediterranean Twist

Add ½ cup chopped Kalamata olives and ¼ cup chopped fresh parsley. It’s more traditional Greek style. I love this version for parties because it feels fancy.

Avocado Add-In

Toss in 1 diced avocado right before serving. It adds creaminess, but it will brown if it sits too long. Add it 15 minutes before serving for best results.

Herb-Forward

Add ¼ cup fresh chopped mint or basil. Mint is surprisingly good with cucumber. It makes it taste like a spa drink. Great for hot summer days.

Protein Boost

Add grilled chicken strips or chickpeas. I often serve this alongside my Labor Day grilled chicken salad, but you can add chicken directly to this bowl to make it a full meal. Chickpeas make it vegetarian and filling.

Dairy-Free Option

Skip the feta and add ¼ cup tahini to the dressing. It adds creaminess and nuttiness. It’s not the same, but it’s still delicious.

Serving & Storage

How to Serve

I usually serve this straight from the bowl at the dinner table—it looks rustic and stays cool. But here are other ways I’ve enjoyed it:

Side Dishes:

• BBQ Chicken Skewers (the acid cuts the smoke perfectly)
• Grilled corn on the cob with butter
• Simple garlic bread
• Cold pasta salad (if you want a starchier side)

Toppings Bar:

When I have guests, I put out: extra feta, red pepper flakes, fresh cracked pepper. Everyone customizes their bowl.

Storage Instructions

Refrigerator:

Store in an airtight container for up to 3 days. The cucumbers will soften slightly after day 2, but it’s still good. The flavors actually get stronger.

Reheating:

Don’t reheat this. It’s a cold salad. Serve it straight from the fridge.

Freezing:

No. The cucumbers will turn to mush. Do not freeze this salad.

Meal Prep:

This is perfect for meal prep. I make a big batch on Sunday, portion it into containers, and eat it for lunch all week. It’s healthy, cheap, and ready to go. I pair it with hard-boiled eggs for a complete lunch.

Pro Tip:

If you’re doubling the recipe for a party, make sure your serving spoon is big enough. Nothing worse than trying to serve a crowd with a tiny spoon. Use a large salad server.

Frequently Asked Questions

Can I use cherry tomatoes instead of regular tomatoes?

Yes! Cherry tomatoes are actually easier because you just halve them. They’re sweeter and have more flavor. I use them when regular tomatoes are out of season or expensive. Just make sure they’re ripe.

Why did my salad get watery?

Salt draws out moisture from vegetables. If you salted it too early or left it in the fridge too long, it will release water. To fix it, drain the liquid before serving. To prevent it, add salt right before serving or use less feta.

Can I make this ahead for a party?

Absolutely. This is one of the best make-ahead salads. Make it 4-6 hours ahead. The flavors improve. Just don’t add avocado until you’re ready to serve.

Is this salad gluten-free?

Yes, naturally. Just make sure your feta and olives don’t have added gluten (rare, but check labels). It’s a safe side dish for gluten-free guests.

Can I substitute white vinegar for red wine vinegar?

You can, but the flavor will be sharper and less complex. Apple cider vinegar is a better substitute. White vinegar works in a pinch, but red wine vinegar is the standard for a reason.

How do I store leftovers?

Store in an airtight container in the fridge for up to 3 days. It’s great for lunch the next day. The cucumbers will soften, but it’s still tasty.
