This wonderfully simple Mediterranean cucumber salad tastes even better the longer it marinates in the fridge! I love this light and refreshing salad because it always makes me think of summertime. When the weather warms up, I start craving this salad more than any other.

Ingredients

Cucumbers – Any variety works, but I prefer English cucumbers because you can leave the skin on for extra fiber. (I asked for English cucumbers in my grocery order, but as you can see in the picture, I worked with what I had!)
Tomatoes – Any variety will do.
Onion – Use any type: red, white, yellow, or green onions all work great.
White wine vinegar – You can substitute red wine vinegar for a similar flavor. Avoid apple cider or distilled white vinegar, as they tend to be too harsh. Rice vinegar might also work well.
Olive oil – Avocado oil or another neutral vegetable oil can also be used.
Dried oregano
Salt
Black pepper

How to Make Mediterranean Cucumber Salad

Prep the cucumbers – If using English cucumbers, you don’t need to peel them. For other varieties, I use a vegetable peeler to remove most or all of the skin because it can be bitter. Cut off the ends, slice in half lengthwise, and then cut into 1/2-inch slices. Place in a medium-sized bowl.
Prep the tomatoes – Core the tomatoes and cut them into quarters. Slice into 1/2-inch slices and add to the bowl with the cucumbers.
Prep the onion – Cut off the ends, halve the onion, and peel off the skin. Cut one half down the middle and thinly slice. Add to the bowl. Save the other half of the onion for another recipe.
Make the dressing – In a small mixing bowl or cup, whisk together the oil, vinegar, oregano, salt, and pepper. Pour over the vegetables and mix well to combine.
Chill and serve – You can eat the salad immediately, but it’s best if it sits in the fridge for at least a few hours. It’s even better after a day or two! You can store it in the fridge tightly covered for up to one week.
