It can. According to the laws of physics, you can indeed put a pineapple on a pizza. If you can't, there must be something within the ingredients to make the entire product pineapple-proof, which is impossible.
I dare you to go to Italy, go into a pizzeria and ask for a pineapple pizza. Then order a real pizza and you will never have pineapple on pizza again. Trust me.
im not going to hate on you, honestly i was not expecting this to even blow up that much. however your kind of thinking will get the two sides to work together to destroy you. but my opinion is 'you do you'
Actually... my brother note WE ARE A ITALIAN FAMILY he decided to put bananas and pickles onto a normal pepperoni, jalapeño, sausage pizza, my father was not happy...
