The Greeks put nothing but tomato, cucumber and olives in their salad (at least at all of the restaurants I went too.) The feta cheese doesn't come already sprinkled all over the salad the way you probably make it at home. It just comes in one huge block sitting in the salad. (I'm not sure if they want you to crumble it up yourself, or if you're supposed to just cutt pieces off it as you go.)
But that's how the Greeks generally make their salad..... and they have olive oil for dressing.
