I'm good with pineapple on pizza. Not every time or every combination, but it satisfies a craving sometimes. Half of the pizza I eat is homemade with either a sliced French bread, tortilla, or sourdough for a crust with whatever random shit/leftovers I find in the kitchen as toppings.
Nah. The tortilla ones definitely look like pizza. The others might fall under flatbread or some other moniker.
I remember when I was in Bologna, Italy in 2008 or so, and the local pizza place we stopped at offered, among other things, slices with big chunks of potato. If actual Italians are putting hunks of tater on a pie, I refuse to feel bad about pineapple.
