The Grilled Stuft Nacho is made up of seasoned beef, spicy nacho cheese sauce, sour cream and crunchy red tortilla strips. They're then grilled into a giant flour tortilla. Easy to carry, bite and devour. Though only available for a limited time at $1.29, they could very well be the next Doritos Locos Tacos. If they dunked them in Doritos dusting, that is.
