This refreshing, light salad is wonderful on its own, but also great with whole wheat pita bread (or tortilla) and plain Greek yogurt. I also enjoyed it on a bed of mixed greens, with a little bit of olive oil and vinegar as dressing.
Preparation tips: Taste each cucumber before chopping it up! If you find one that has bitter skin, peel it before dicing. One of my three cucumbers, strangely, tasted bitter and I wish I had removed the skin on it before adding it to the rest. At first, I chopped the tomatoes and cucumbers into pretty big chunks, but I later found that I enjoyed the salad more when they were chopped more finely (see the cucumber salad on top of the mixed greens). I suggest chopping them into small pieces from the beginning.
Make it dairy free/vegan: Skip the feta.
