Gonna go all combinations.
Sausage, Green Pepper, and Onion. If a pizza joint fucks this up, never go back.
White Pizza with Pesto, Shrimp, and Tomatos (a specialty of a place near where I lived in Brooklyn. strangely all of their other pizza topping were kinda bad, but this? this was always amazing.)
Batter Fried Eggplant. Try it!
Pepperoni and Mushroom. This also on the basis of a pizza joint in New York near where I used to work. The spicy grease from the pepperoni soaks into the mushrooms. So good.
