If you have ever eaten at a Mediterranean restaurant, you will recognize this delicious side dish! I serve this salad with my favorite Instant Pot Chicken Shawarma, Instant Pot Yellow Rice, Classic Hummus, and naan bread at home all the time.

Recipe ingredients:

Sliced cherry tomatoes, cucumber, red onion, kalamata olives, oregano leaves, sea salt, red wine vinegar, olive oil, and crushed red pepper in white bowls.

I just love the vibrant colors of these cherry tomatoes! Using cherry tomatoes release less liquid than Roma tomatoes will, but feel free to substitute is needed.
An almost seedless English cucumber is perfect for this dish, and takes much less time since you don’t need to scrape out the seeds or peel off the skin. Just slice into quarters and you’re done.
Kalamata olives are the traditional Greek olives used in most recipes. You can however use black olives if you prefer.
I used red wine vinegar, but balsamic will also work.

Recipe notes & tips:

If using a regular cucumber: peel off the skin, cut in half length-wise and scoop out the seeds with a spoon.
If making ahead of time: chop the cucumbers and olives, then store in the refrigerator until ready to use. Onions can be sliced and stored as well. Do not slice the tomatoes ahead of time, they do not belong in refrigerator. Slice them just before you are ready to assemble the salad.
If you do not have fresh oregano, fresh Italian parsley or basil would work as well.
