In the 1990's, Pizza Hut was listed as being fourth in sales in the top fifteen fast-food companies in the United States. Even though the recipe for pizza was imported from Italy, this high ranking just goes to show the American people's infatuation with this one-pan food. A pizza, or a pizza pie as it is sometimes called, is basically a crust made from flour, yeast, salt, and water which is kneaded, then rolled out into a round shape. The crust is then covered with spicy tomato sauce and cheese and baked in an oven.
Pizzas come with a variety of toppings nowadays, instead of just the basic cheese flavor.
Toppings include mushrooms, onions, anchovies, pepperoni, black olives, green olives, jalapeno peppers, sausage, chicken, hamburger, and many more. The crust has also changed. You can now get a pizza with a crust which is stuffed with cheese, a thin crust pizza, a thick crust pizza, a deep-dish pizza, and more. Pizza is even made by using French bread instead of the traditional crust. History shows that the early Greeks prepared and ate a flat bread which was topped with herbs and oil and then baked.
