Canned because I prefer the soft texture of it. On pizza because it works amazingly well warm and on tomato sauce (although how I have no clue because even just writing it makes it sound revolting but it tastes so so good).
Pineapple upside down cake and pineapple bread sound really tasty. Though Im not the biggest pineapple fan. Im also kinda sad you didn't include Spongebob's pineapple ;-;
