Pizza toppings are the ingredients added to the base of a pizza, which typically includes dough, sauce, and cheese. Common toppings include meats like pepperoni, sausage, and ham, as well as vegetables such as bell peppers, onions, and mushrooms. Some people also enjoy unique toppings like pineapple or anchovies. The choice of toppings can vary widely based on personal preferences and regional styles. For example, Neapolitan pizza often features simple toppings like fresh basil and mozzarella cheese, while Chicago-style pizza may include a thicker layer of toppings and cheese.
