Yep...pineapple with some spicy pep (and other toppings work well with it...maybe some spicy chicken, etc.) it's real good as a pizza topping choice (fresh pineapple only...canned is just wrong). Also pineapple on pizza is actually a Canadian invention (originally marketed here in Ontario, Canada in the early 1960's).
And with all the negative pineapple on pizza crap kind of reminds me of the fuss that was said many years back with some that tried to spew..."real men don't eat quiche" BS. It's just a different kind of way of making an egg dish.
You can put anything on pizza, your the one eating it.
