There's a reason this salad keeps popping up on everyone's summer table right now. Crunchy mini sweet peppers and cool cucumbers get tossed with briny feta, kalamata olives, and a bright lemon dressing, and the whole thing comes together in about fifteen minutes with zero cooking involved. It's the kind of side dish you can throw together while the grill is heating up, and it disappears fast every single time.
If you've seen versions of this salad floating around social media, this one leans into its Mediterranean roots with olives, oregano, and a proper lemon and olive oil dressing instead of a sweeter, more neutral vinaigrette. It's crisp, tangy, a little salty from the feta and olives, and endlessly easy to customize. Serve it alongside grilled chicken, lamb kebabs, or a piece of pan-seared salmon, or spoon it into a pita with hummus for a quick lunch.

Ingredients You'll Need
This salad uses simple, fresh produce plus a handful of pantry staples for the dressing. Here's what goes into it and why.
For the salad:
- Mini sweet peppers (12 oz): These give the salad its signature crunch and natural sweetness without any heat. Look for a mixed bag of red, orange, and yellow peppers for the best color.
- Mini cucumbers (2, or about 10 oz): Persian or mini cucumbers have thin skin and fewer seeds than regular cucumbers, so there's no need to peel or seed them. Regular cucumbers work too; just peel and seed them first.
- Red onion (0.25 cup, thinly sliced): Adds a little sharpness. If raw onion is too strong for your taste, soak the slices in cold water for 10 minutes first to mellow the bite.
- Feta cheese (0.5 cup, crumbled): Classic Mediterranean flavor. Block feta packed in brine tends to taste fresher than pre-crumbled feta.
- Kalamata olives (0.25 cup, halved): Bring a briny, savory note that balances the sweetness of the peppers.
- Fresh parsley (2 tbsp, chopped): For a fresh, herby finish.
For the lemon dressing:
- Extra virgin olive oil (3 tbsp): Use a good-quality oil since it's doing a lot of the flavor work here.
- Fresh lemon juice (1.5 tbsp): Bottled juice works in a pinch, but fresh has more brightness.
- Red wine vinegar (1 tbsp): Adds acidity and depth alongside the lemon.
- Dried oregano (0.5 tsp): A staple Mediterranean herb that pairs beautifully with feta and olives.
- Salt and black pepper: To taste, adjusted at the end since both the feta and olives already bring salt.
Substitutions and variations: Swap feta for goat cheese if you want something creamier, or leave the cheese out entirely for a dairy-free version. Green olives can stand in for kalamata. No fresh parsley on hand? Fresh dill or mint both work nicely with this flavor profile. For extra protein, stir in chickpeas or diced grilled chicken to turn this side salad into a light lunch.
How to Make Mediterranean Mini Sweet Pepper and Cucumber Salad
Step 1: Prep the vegetables. Wash the mini sweet peppers, slice off the tops, and remove the seeds. Slice the peppers into thin rings; a sharp paring knife makes this much easier than a chef's knife since the peppers are small. Trim the ends off the mini cucumbers and slice them into thin rounds. Thinly slice the red onion. Keeping all the pieces roughly the same thickness helps the salad hold its texture once it's dressed.
Step 2: Combine the salad base. Add the sliced peppers, cucumbers, and red onion to a large mixing bowl. Toss gently to distribute the vegetables evenly.
Step 3: Whisk the dressing. In a small bowl or jar, whisk together the olive oil, lemon juice, red wine vinegar, oregano, salt, and pepper until well combined. If using a jar, simply seal the lid and shake until emulsified.
Step 4: Dress the salad. Pour the dressing over the vegetables and toss well, making sure everything gets an even coating.
Step 5: Add the feta, olives, and parsley. Scatter the crumbled feta and halved kalamata olives over the top, then add the chopped parsley. Toss gently one more time so the cheese doesn't break apart too much.
Step 6: Chill and serve. For the best flavor, let the salad rest in the fridge for at least 15 to 20 minutes before serving so the vegetables can soak up the dressing. It's also perfectly fine to serve it right away if you're short on time.
Tips for the Best Results
- Slice everything evenly. Uniform, thin slices mean every bite has a good ratio of crunch to dressing.
- Salt the vegetables lightly before dressing if your cucumbers are especially watery, then pat them dry. This keeps the salad from turning soggy in the fridge.
- Add delicate ingredients last. Feta and herbs go in after the dressing so they don't get crushed during tossing.
- Let it rest. A short chill in the fridge lets the flavors meld and actually makes the salad taste better than serving it immediately.
- Taste before serving. Feta and olives vary in saltiness by brand, so adjust the added salt at the end rather than at the start.
- Use good olive oil. Since there's no cooking to mellow the oil's flavor, a fruity, good-quality extra virgin olive oil makes a noticeable difference in the final dressing.
Storage and Reheating
This salad is served cold and doesn't require any reheating. Store leftovers in an airtight container in the refrigerator for up to 2 days. Because cucumbers release water over time, the salad is at its crispest within the first 24 hours; after that, it will still taste good but will be noticeably softer and a little more liquid will pool at the bottom of the container. Give it a quick stir before serving again, and drain off any excess liquid if needed. This salad isn't a good candidate for freezing, since the vegetables will turn mushy and watery once thawed.
If you like to meal prep, you can slice the vegetables and make the dressing up to a day ahead, storing them separately, then combine everything with the feta and olives right before serving for the freshest texture.
Frequently Asked Questions
Can I make this salad ahead of time? Yes. You can prep the vegetables and dressing a day in advance and store them separately in the fridge. Toss everything together, including the feta and olives, no more than a few hours before serving for the best texture.
Do I need to peel the mini cucumbers? No. Mini and Persian cucumbers have thin, tender skin, so peeling isn't necessary. If you're using a regular cucumber instead, peeling and seeding first will give you a similar texture.
What can I use instead of feta cheese? Goat cheese is a good substitute if you want a creamier texture. For a dairy-free version, simply leave the cheese out; the salad still holds up well thanks to the olives and dressing.
Is this salad keto and low-carb friendly? Yes, this salad is naturally low in carbohydrates, since it's built almost entirely on non-starchy vegetables, olive oil, and cheese, making it a good fit for keto or low-carb meal plans.
Can I turn this into a main dish? Absolutely. Add a protein like grilled chicken, shrimp, or chickpeas to turn this light side salad into a satisfying lunch or dinner.
Why is my salad watery? This usually happens when the cucumbers sit too long in the dressing. Salting and patting the cucumber slices dry before mixing, and serving the salad within a day or two, will help keep it crisp.
Are mini sweet peppers spicy? No. Mini sweet peppers are a sweet pepper variety with no heat at all, similar in flavor to a bell pepper but smaller, thinner-walled, and slightly sweeter. If you want a little kick, add a pinch of crushed red pepper flakes to the dressing.
