Ummmmmm okay. That’s not a good analogy at all. I suppose you think anchovies on pizza isn’t really pizza at all.
What is your requirement for a pizza to be a pizza?
Anchovies is more or less, okay, if you like them, I guess; at least it’s something that an Italian “might” use on a pizza, but don’t.
A "normal" pizza is a flatbread dough, covered in tomato sauce or tomatoes and cheese ( usually mozzerella ), some olive oil sprinkled on it, and baked. Sometimes pepperoni, Italian sausage bits, onions, mushrooms, or combinations of such, ad added to the toppings.
The crust varies from extremely thin to a bit thicker, depending upon where in Italy it originated.
Chicago "deep dish" pizza is a VERY recent, AMERICAN invention and NOT for real pizza...though a whole lot closer to it, than the California thought up BBQ chicken "pizza" etc. and the abortion that tops this thread.
