It's that special day that only comes once a year when the beloved pizza pie is officially recognized with it's own celebration day.

According to Collins English Dictionary, Pizza is defined as... a dish of Italian origin consisting of a baked disc of dough covered with cheese and tomatoes, usually with the addition of mushrooms, anchovies, sausage, or ham. The word pizza comes from Italian, perhaps from vulgar Latin Picea which means the blackening of crust by fire.
