I have something controversial to say:
Meat and pizza should never go together.
Seriously: pizza loaded with tons of tomato sauce, olives, peppers, onions, mushrooms is the best. It doesn't need meat. And meat certainly doesn't need it. Please keep your pepperoni and sausage to yourself. And also all those other words that are just fancy words for sausage.
(And while we're at it: mac and cheese should always be vegetarian.)
