Nuke CommunityNEW Pineapple on PizzaThis annoys me, an Italian chef in Australia refused to put pineapple on a pizza. While my sub was on a Mediterranean run, I had a pizza in Italy and was not a fan. This is not restricted to Italian chefs I have frequently heard that pineapple does not belong on a pizza. Italian Chef Loses Job After Refusing to Put Pineapple on Pizza favorite pizzas in order are pepperoni, Hawaiian (pineapple and Canadian bacon) then meat lovers. I prefer thin crust as I like it a bit crunchy. Most of the pizzas I eat are from the grocery store but the best I have had are from hole-in-wall pizzerias.Comments/opinions?
