There’s a video going around YouTube of a street food guy who makes breakfast burritos (video posted above). The main difference in this guy’s burritos is that he puts a layer of cheese onto a griddle, then puts the burrito onto that layer of cheese, creating a layer of crispy cheese stuck to the outside of the burrito. The toasted cheddar chalupa basically steals that idea.
It’s just a chalupa with the toasted cheese on the outside. You can taste the cheese and it does add something, but it’s basically the same thing as a regular chalupa. I paid $2.50 for my toasted cheddar chalupa. I don’t know if that is more or the same price as a regular chalupa, but it should be at most twenty-five cents more than what a normal chalupa costs, if not the same price.
Overall, this is just advertising. The toasted cheddar changes almost nothing to the base product.
