In Knoxville Tennessee, Taco Bell is testing a "Grilled Stuft Nacho" which contains beef, tortilla strips, cheese, and sour cream all wrapped in a soft flour tortilla and it's the next best thing to them literally making a giant Nacho chip and handing it to you. Although it's still in its testing phase, I have faith that Taco Bell will do the proper American thing, and get this overly self-indulgent food item to become a reality.
