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.)
There’s also a “Canadian” pizza which is usually Pepperoni, Bacon and Mushrooms, sometimes made with a Cheddar Cheese/Mozza blend depending on the place
Well I have definitely had pepperoni and bacon on my pizza. Those ingredients would work well on a cheesesteak, I would eat mushrooms on a sandwich. There was a place near me with “stereotypical ethnic” pizzas and sandwiches that had Canadian pizza on it if I remember correctly. They had Chinese, Greek, Mexican etc. they also had celebrity/historian sandwiches that were decent.
