Haven't had pineapple pizza but I've had warm pineapple on its own and I hated it for some reason, so my hopes of liking it on pizza are looking pretty dicey. Maybe if just the pineapple was magically cold I wouldn't mind it, just mentally treat it like two separate foods. Pineapple on its own is nice despite them teeming with tiny needles and I have to stop myself from inhaling too much pizza at once if I want to sleep at night, but warm pineapple is a no from me, dawg.
