Pineapple on Pizza is good. Really it is.

I was gonna say pineapple pairs well with green peppers on pizza, but that jalepeno combo looks retarded delicious.

Agreed! When I was a kid my parents always got hawaiian pizza with pineapple, ham, and cinnamon and it was amazing. Now I usually get pineapple + bacon if I want something like that.

Not my first choice, but I enjoy eating it when offered. It "scales up" pretty well, too, with higher-quality meats, and other fruit/meat combos are also tasty. My go-to will always be pepperoni, but being a pizza is simply an open-faced sandwich (fight me), it lends itself to all sorts of toppings.

Pineapple is whatever, but cinnamon? On pizza?

I won't defend it on pizza because I never had it, but cinnamon is used a ton in savory and spicy dishes. It's a very versatile spice, not just for sweets and coffees. I could see the potential usage... Maybe

GOAT Pizza. As a vegetarian, pineapple is a must on my pizza. I've even included it when I ordered chi style pizza (actually don't do it, does not belong in Chicago style pizza)
