Although a food as divisive as Hawaiian pizza might seem distinctly American since it shares the name of a US state, it's actually an invention with Canadian roots.
The late chef Sam Panopoulos moved from Greece to Canada when he was in his 20s, and he first put pineapple on pizza in 1962 at one of his Ontario restaurants. Eventually, he added ham, too, Atlas Obscura reported.
"We just put it on, just for the fun of it, to see how it was going to taste," Panopoulos told BBC News. "We were young in the business and we were doing a lot of experiments."
Per BBC News, the "Hawaiian" part of the pizza's name is a nod to the can of pineapples that was first used in its creation.
