I’ve seen these before, you may have too - someone walking around a fair or festival with a snack size bag of Tostitos (or Fritos) and digging in with a fork. This is a Tijuana street food favorite that’s like a Frito pie in a bag - hands clean, portable. I think they are in the category of a Lunchables - questionable redeeming nutritional value. Oh, but we’re talking Fair food, so who cares!
Rose’s has this handy delight.
