This recipe just kind of popped into my head since I had some leftover chopped tomatoes, olives, marinated cubed Feta and Fillo Cups.
Place a few cubes of marinated Feta, Kalamata Olive and Tomato in each Fillo Cup. You could also add a slice of Greek Pepper (pepperoncini)
These also were great! You could also try it with different flavored Feta, like a Sundried Tomato.
