Combine 2 cups of grape/cherry tomatoes or chopped tomatoes with 2 cups cubed feta cheese and 2 cups diced green onions. Sprinkle with oregano, a bit of salt to taste (feta is very salty), and freshly ground pepper. Squeeze a quarter of a lemon over the salad and then drizzle with olive oil. Serve as an appetizer with a loaf of good bread.
I don't know the original origins of this salad, but we enjoyed my sister's version when we were vacationing with family. I actually remembered to make it when we got home!
