Sushi pizza is a Canadian dish that originated from Toronto and a fusion of sushi and pizza often served in the Greater Toronto Area, conceptualized by Kaoru Ohsada no later than May 1993 as a Nami Japanese Seafood Restaurant chef.[1] It uses a slightly crispy yet chewy fried rice patty as the base and is topped with a layer of sliced avocado, a layer of sliced salmon, tuna or crab meat, a drizzle of blended mayonnaise and wasabi powder and is served in wedges. Nori, pickled ginger, and roe are sometimes also served as toppings or sides.[2][better source needed]
