Vaguely resembling its Chicago-based cousin, the Italian pizza doesn't rely on thick, spicy sauce, pounds of cheese and mountains of pepperoni. The true Italian pizza is lighter and kinder to the waistline. The term pizza was thought to originate from the Latin word, pinsa, meaning flatbread. Originally, Italian pizza crust was made from little more than flour, water and yeast, topped with olive oil and baked in a hot brick oven.
The use of tomatoes didn't come about until the late 1800s. Before that, they were thought to be poisonous. Once Italian pizza maker, Rafaele Esposito, made a pizza for the Queen using the colors of the Italian flag, red tomatoes, white mozzarella cheese and green basil, all bets were off and people began adding all sorts of ingredients to their crusts. Today there are pizzas topped with everything from apples to yellowfin tuna.
