In a bowl, pour corn chips to cover the bottom of the dish. Ladle on hot chili, sprinkle with cheese and onions. Top with yellow mustard and jalapeno slices if you desire.
So do you live in the South? Have you tried Frito Pie's before? What do you top yours with? Better yet, share some of your guilty pleasures. I would never invite someone over for a Frito Pie, but I would sure make one if you hinted you wanted one ;)
Link to Wendy's Chili is perfect for Frito pie.
