Frito pie

Frito pie is a dish popular in the Midwestern, Southeastern, and Southwestern United States, whose basic ingredients are chili, cheese, and corn chips . Additions can include salsa, refried beans, sour cream, onion, rice, or jalapeños. There are many variations and alternative names used by region. Frito pie can be prepared in a casserole dish, but an alternate preparation can be in a single-serve Fritos-type corn chip bag with various ingredients as toppings. The exact origin of the frito pie is not completely clear. The oldest known recipe using Fritos brand corn chips with chili was published in Texas in 1949. The recipe may have been invented by Daisy Doolin, the mother of Frito Company founder Charles Elmer Doolin and the first person to use Fritos as an ingredient in cooking, or by Mary Livingston, Doolin's executive secretary. The Frito-Lay company attributes the recipe to Nell Morris, who joined Frito-Lay in the 1950s and helped develop an official cookbook which included the Frito pie.
