Since I own a pizza restaurant, I can authoratively comment on this subject. The right sauce, toppings, crust et all are vital to a great PIZZA, but there's more then just the pizza. You should strive to create the best pizza experience. It's a combination of textures & flavors. An oft overlooked part of a great pizza experience: The right drink.
If you're a soda drinker, Root Beer makes any pizza taste better. Even if you don't like Root Beer, there's something about the combination.
If you're into other stuff, the right beer can make a pizza just about perfect. Even an unevenly cooked frozen pizza with a black bottom tastes ok if it comes with the right beverage.
That aside, a simple but good pizza combo I enjoy is pepperoni & green peppers. The pepperoni must be on top of the cheese, at least half of it, so that they cook crispy.
