I love pizza so much it is yummy in my tummy mmmmmmm.
You got that right. Although you can find it all over the US it is traditionally an Italian dish.
Yes I actually worked at a Neapolitan pizza place that used Italian ingredients and made it in the tradition of Naples Italy.
Very cool. As of 2009 the European Union recognizes the Neapolitan pizza as a Traditional Specialty Guaranteed dish. What an honor.
I didn't pay much attention at work lol, please tell me more about Neapolitan pizzas.
Well there is an organization aimed at protecting the true Neapolitan style pizza. It was organized in 1984. 
Cool. Do you know any other styles of pizza?
Theres deep dish in Chicago. Since pizza is so popluar in North America and Europe lots of places have their their own twist to their pizzas.
How long ago did deep dish become a thing?
Deep dish can be dated back to around the 1940's. I love how many different toppings there are. You can throw on different vegetables, meats, and cheeses to change things up.
