Brown 1 1/2 lbs ground beef. Mix in taco seasoning and cook according to directions on package.
Layer in a casserole dish in the following order: Fritos chips, meat mixture, shredded cheese. Repeat layers once again.
Bake at 350°F for about 15 to 20 minutes or until cheese is bubbly.
After removing from oven I added more cheese on the top.
