Now that I'm sequestered far away from any and all angry Italians, I can continue. Greeks invented the pizza by putting cheese and olive oil (OF COURSE!) on pita bread. Then the Romans ran with it, but that still wasn't the pizza we know of today.
That is Italian, or rather Neapolitan. Either way, lots of people realized it was a great idea to throw cheese and olive oil on bread.
Today, I am thankful for pizza. I got one of those really cheap Totino's cheese pizzas and sauteed some onions for it. Really, pizza is a great idea. You have bread, tomatoes, vegetables, meat, and dairy, all in one food. And if you're not eating Chicago pizza you can just pick it up and eat it.
Pizza is also the most awesome food ever.
Especially if someone was smart enough to put cheese in the crust.
