16. XXL Grilled Stuffed Burrito
Not just any burrito can bear the weight and responsibility of these three letters. But the XXL grilled stuffed burrito lives up to its name. A tender layer of steak is marinated to perfection and topped with a generous layer of avocado ranch, pico de gallo, and guacamole. And cheese. Of course there's cheese. This isn't Taco Bell's first rodeo, folks.
