What? You only eat meat and potatoes, Moony?Lol, I don't eat pasta either. Yuck
But to answer the question: red sauce, onions, sliced black olives, mushrooms, mozzarella, parmesan.
I also like that white sauce with mushrooms and spinach one @ShrekDawg mentioned. Been a while since I've had that but it's mouth-wateringly unforgettable! (Mouth-wateringly, that's a word. Right? I thought so!)
At our local Pizza Inn you can get taco pizza which is real good and also dessert pizzas, which are ahh-MAAAAAY-zing! So there's that.
