User: What makes for a great pizza?
Assistant: There are many different variations of pizza. Many would say that the crust and sauce are more important than the toppings when considering what makes a pizza great. Toppings (pepperoni, mushroom, sausage, pineapple, etc.) are generally pretty standard, with little variation by source or region, though premium ingredients may be had my many pizza chefs, these are not considered here because premium toppings may not be available to every pizza chef.

The crust and sauce, however, are nearly limitless in variation.  From thin crust to thick crusts, to bright or spicy sauce; a pizza chef may make their mark with excellent pizza on the foundation of a well made crust with a well flavored sauce.
