Keto Spicy Tuna Sushi Burrito

Searching for a way to satisfy your sushi roll craving without compromising your keto or low-carb diet? Surprisingly, you don’t have to settle for a simple plate of sashimi, a plain poke bowl or a seaweed salad topped with raw fish to stay within your macros.

While many fast-casual restaurants offer “healthier” versions of this Japanese specialty, going with a takeout option isn’t necessarily the best idea. After all, you don’t necessarily know all the ingredients that go into the menu items listed.

However, by creating your own sushi burrito right at home, you can still enjoy the classic flavors of a spicy tuna roll (or salmon, if you’re concerned about mercury levels) without having to worry about going overboard on carbohydrates. By swapping out traditional sushi rice for the cauliflower-based alternative, this recipe keeps the net carb count at only 5 grams per serving. Plus, fresh veggies provide fiber, micronutrients and a crispy textural element that take this sushirrito to the next level.

Don’t worry about your taste buds not getting enough action, either. Fresh, vitamin B12-rich tuna coated in a homemade version spicy mayo (thanks, mayo and sriracha!) will make your mouth water with each and every bite. If you want to kick the heat factor up a notch, you can even add a few sliced jalapenos before you get rolling.

By the time you’re finished in the kitchen, you’ll be left with a restaurant-worthy, keto-friendly sushi burrito that puts a unique twist on Japanese cuisine.
