What is red and white and green and black? Greek salad! A mixture of tomatoes, cucumbers, red onions, and olives topped with feta cheese, Greek salad is usually dressed with olive oil and lemon juice and sometimes a pinch of oregano. This healthy and crunchy combination is a Summer time staple. Be sure to use only the freshest and best tasting ingredients. Hearty and filling, a Greek salad can be used as an entrée or as a side salad.
