Pineapple is native to South America, so probably not.

Pizza Hawaii

They did a taste test, and noticed it had fresco cheese instead of mozzarella

90% sure it's tomatoes. They are not native to Europe and were only introduced in the colonial era.

Required? I'd go with water, flour, yeast, salt, olive oil.

After that it becomes difficult as a pizza bianca with nothing else but olive oil would be strange, you generally get at least garlic and some cheese, but that's the minimal set of ingredients shared by every pizza.

OTOH, cheese might actually be a requirement, can't think of a cheese-free pizza right now. Oh this is going to piss of the vegans.

Things may or may not get more complicated, depending on what you consider Pizza, if you include Flammkuchen which doesn't require yeast or olive oil, and also comes cheese-free by default, instead using some sort of sour cream (and onions and ham). If you ever manage to get your hand on Federweißer, that is a killer combination.

may have been eaten with fruits such as pomegranates or dates, or dressed with spices and a type of pesto sauce

i would say tomato and cheese and think i see both

I don’t know which ingredients are required but I don’t think they had tomatoes at that time. Wasn’t they discovered in the new world?

We are all pizzas on this blessed day

Better than Papa John’s
