Pineapple on pizza, or what they called "Hawaiian pizza" was my first introduction to pizza and has been the only pizza I would have growing up. It's only in my 20s did I start trying out other toppings and combinations. So now pineapple or hawaiian is my second pick, why? Is it that good? No absolutely not, I can think of 15 other pizzas and combinations that are better than it, but because hawaiian will always bring me happy childhood memories.
Watch out with pineapple on pizzas, there were people beaten off in Italy for this : .
Also, never admit you happened to break spaghettis in half so they can fit in your pot, they are very serious with this kind of things
