If you're not in Italy, it's not really pizza.
If you are in Italy, the pizza will not even closely resemble what Americans expect. Generally, it is just a seasoned flat bread (and never any toppings).
When I was in the army stationed in Germany in the early 70's, I was sent to a non-touristy part of northern Italy to install a radio-intercept station. One local cafe offered "Pizza Americano" on their menu. I ordered one to see what it was. Imagine a plate sized flat bread with the edges folded up to form a circular dam, with a lake of molten grease contained therein(with some mystery meats floating in it)! There was no way we were going to try to actually consume that thing.
