This Korean spicy tuna kimbap recipe has a bright and spicy mayo sauce with canned tuna and crunchy vegetables. It takes less than 30 minutes - perfect for a quick lunch or a busy weeknight! All you have to do is steam some rice, chop some veggies, and bust out a good ol' can of tuna. And if you're anything like me, you don't even bother plating it; I eat it straight off the cutting board.
