I really enjoy pizza, but I do not know much about it.  Do you know where pizza first came from?
The very beginning was actually all the back with the Romans. It was called "panis focacius" and was a flat bread with topping put on it. 
Oh wow, that is really far back.  I guess I just asummed it came from Italy
In the late 18th century, what you would consider modern pizza was first made, and that was made in Naples. They put tomato on top of the focaccia.
So earlier pizza was more of a thin crust type of pizza.  My favorite pizza is Chicago style.
I like that, too! The person who founded Pizzeria Uno, Ike Sewell, says they invented it in 1943, but there is dispute over when it actually did occur.
