Sushi burritos were created in 2008 by Peter Yen, founder of the Bay Area’s popular Sushirrito, as a way to combine two of his favorite foods: sushi and burritos. You’ll need a bamboo sushi-rolling mat, which you can find at kitchenware stores, Asian grocery stores, or online. This easy sushi burrito recipe includes salty, crunchy, fresh, sweet and creamy notes by using avocado, potato chips, mirin and cucumber to accompany the fresh tuna, nori and rice.
