Today, October 11, 2014, is National Sausage Pizza Day. Pizza is an oven-baked flat bread usually topped with tomato sauce, cheese, and various toppings. The modern pizza was invented in Naples, Italy, and the dish has since become popular in many parts of the world. The term 'pizza' first appeared "in a Latin text from the southern Italian town of Gaeta in 997 AD. It claims that a tenant of certain property is to give the bishop of Gaeta twelve pizzas every Christmas Day, and another twelve every Easter Sunday".
