Protip: panfry your pineapple in butter until browned. THEN add to pizza. Or, just eat it straight. Your tastebuds can thank me later.
I come back to point a very terrible fact. I'm very gutted that it has come to this.. People prefer having pineapple on pizza... Its a very sad day. We must have this resolved, for the greater good, for our futures! Say No To Pineapple (on pizzas)!
