What does pizza look like?

Pizza is typically a circular, flat bread covered with tomato sauce and cheese. Other toppings, such as pepperoni, mushrooms, onions, and bell peppers, are often added. The pizza is then baked in an oven until the cheese is melted and bubbly. The dough may be thick or thin, and the crust may be either crispy or chewy. Some pizzas are made with a gluten-free or whole-wheat crust.
