This is one of those recipes that just tastes good, although it's probably not so good for you.  And it tastes better two or three days later.  I don't even remember where I came across the recipe, but it's one I've made for dinner for 20 plus years.

The basics-
chili
cheese
onions
fritos or frito style corn chip

Pre heat oven to 350.
Start with a layer of fritos.  Next add in layers (in no particular order) chili, cheese, onions and more fritos.  I always end with a layer of cheese, but I never layer in the same order.  Bake the whole mess until hot all the way through and bubbly.

Ideally I would use homemade chili, but we use canned turkey chili a lot too.
