I love pizza! I am actually a pizza snob due to the fact that I grew up in the NY metropolitan area. 
Then I supposed you will turn your nose up at the idea of frozen pizzas as opposed to fresh, pizzas such as DiGiorno.
Eh, since I moved from there, I have learned to tolerate some frozen pizzas. When did the pizza first come to fruitation?
The earliest recorded usage of the term to refer to food was in the 10th century, no surprise, from a small Italian town called Gaeta.
Wow! That's was centuries ago! Was it made the same way back then like it is now?
Considering today's ULTRA MEGA DEEP DISH BACON WRAPPED HEART ATTACK SPECIAL pizza and traditional yeasted flatbread pizza, yes I'd say they're different.
LOL!! That sounds DELISH!!! What else can you tell me about pizza?
Pizza is so important to Italy that in 2009, they successfully lobbied it to become a Specialty Guaranteed dish with the EU.
