Cheese, salami and other meats, mushrooms, spicy sauces and spices.
Nowadays mostly these are my favorites pizzas.
I remember trying (eating) pizza with pineapple topping too (a few years ago), but as I currently remember, I have not tried banana pizza topping so far.
Either way, there are many kinds of pizza flavors. I have not tried many kinds of pizza flavors yet.
Nowadays I do not eat pizza often, but sometimes good to try new pizza flavors. Especially if its a homemade oven baked pizza.
