I might be repeating myself saying that I like to look into the fridge to see what else is left in there and use it up before it goes bad. That's how those little burgers turned out which I served as an appetizer.
I posted another type of snack a while ago while being in Pasadena. Check it out here.
feta cheese slices
freshly ground salt and pepper
extra virgin olive oil
black olives, pitted
Preheat the oven to about 400 F. (200 C.)
Place the eggplant slices on a non-stick surface on a grid that will go into the oven. Sprinkle with a little bit of salt.
Put the feta cheese slices on top and add a few drops of olive oil. Next come the tomato slices, seasoned with oregano, salt and pepper.
Cut the olives in half and decorate the snack burgers with one olive each and once again, sprinkle with olive oil.
Place them into the preheated oven and bake until the tomatoes start to build a little crust.
Enjoy with some bread as an appetizer or a snack instead of chips.
