Pretty much you make some chili, any kind you want and pour it on Fritos. I like putting my cheese on the chips first so it gets all melty and sticks to the chips better.
I love Frito Pies cause they're easy, fast, and cheap. You can eat with a fork or get really messy and eat with your fingers; which is my favorite. I loved it as a kid and I love it now so I feel comfortable saying anyone would like it. Matt and I have also had Extreme Frito Pie where we make it the base of nachos and add lettuce, sour cream, tomatoes, and other fun things. This would also make it go further and obviously make it more healthy as well. Enjoy!
