Greek
Greek pizza can either be pizza with many Greek toppings, such as feta cheese (be sure to get feta cheese from a goat, not the cheap stuff from cows as the taste is very different), tomato, green peppers, onions, spinach, often broccoli and most importantly Kalamata olives.
Greek pizza can also refer to pizza baked in a pain creating a, oily chewy type of crust.
