There are very few things that belong on pizza. Besides, pepperoni's, bacon, very thinly sliced ham and a few others that I personally don't like but I think do belong like sausage And if you're a freak, Peppers.
they dont, but weird people do be doing weird things in a daily basys, the moment someone start thinking that pineaple on pizza is a good thing they are already a lost case, if they decide to put anything else i wont be surprised
