Crispy crust with no fillings of any sort (don't really care about whether it's 'white' or whole wheat, just no cheese or anything else stuffed in it), tomato sauce, cheese, pepperoni. I don't mind some added things (veggies, bacon bits and the like), but I don't like deep dish. I've had meatlovers pizzas with thick chunks of ham; it's gross. Too much stuff.
Edit: Oh, and no jalapenos, pineapple, anchovies or mushrooms.
There's a New York style place here that does a honey mustard & chicken pizza that is TDF. And another sort of posh place does one called Shepherd's Pie with potatoes and carmelized onions on it, also TDF. They have one with spaghetti & meatballs on it too, pretty good if only for the novelty factor.
But if it's just delivery like from Papa John's or whatever I like the thin crust veggie lovers or regular crust meat lovers. I order it well done. If the cheese isn't nice and melty and brown I'm not into it.
