Fry up some ground beef and sprinkle in some onions to sautee with it, and chili powder to taste.
Spread the beef mixture on a plate, cover with Fritos, then on top of the Fritos put a layer of grated Mexican or cheddar cheese, depending on you preference. Microwave for a minute or until the cheese is melted on top.
There you have it. If you like beans in your chili, you can add those to the beef mixture and get ready to produce some methane.
