So, a Greek guy in Canada made an Italian staple into something that he thought would represent a Hawaiian cuisine (even though it was just the can, many people naively believe it truly is a Hawaiian dish)
Once someone told me they thought that’s how they ate their pizza over there. Lol.
Nevertheless, if I were in Canada at that time, I would have visited his restaurant and ordered one of the originals. It’s not the best pizza topping but it is also not the worst. (I hate anchovies, fish of any kind or mushrooms on my pizza. Mushrooms are good in other dishes.)
Ham is cured, which is considered processed.
Not OP, but it could be a taste thing:
In the US it’s frequently wet cured to save money. At the deli there are a lot of varieties of ham that mostly just taste sweet, with no noticeable ham flavor or saltiness. This is what usually ends up on Hawaiian pizza.
I didn’t think ham had to be cured necessarily… Like when they cook a pig over a fire, are you not eating ham at some point (I assume it depends on what part of the pig?)? I don’t know.
