(My own concoction)
cucumbers, tomatoes, kalamata (or in this case Calamata) olives,
Feta cheese, sliced red onion, chopped fresh mint, Olive oil and red wine vinegar.
Use your own judgment as to the amounts. I like to keep things in balance and the pieces small enough so that you can have more than one taste in your mouth at once.
Toss these all together and you have a nice summer salad. We will be eating this again.
