Frito Chili Pie, also called Frito Casserole or sometimes even a taco bake recipe consists of chili, topped with cheese, and finished off with Fritos corn chips, and any other toppings that your hungry heart desires. Now for my version, I put together a super quick homemade chili in a skillet before transferring it to a baking dish to make a layered taco casserole. Some people call it walking taco casserole, but I've always understood that to be chili and taco fixings placed into an individual-size Frito or Doritos bag and eaten that way.
