A traditional walking taco is made in the bag of chips. Most use a single serving size bag of Doritos or Frito chips. This casserole uses the same concept of being an easy one dish meal, but is made in a skillet or baking dish rather than in the chip bag. I topped this walking taco casserole with gluten free tortilla chips, lettuce, tomatoes, olives and extra cheddar cheese. You could substitute a different type of gluten free chip and also add avocado on top too.
