The original Fritos Burrito
The Fritos Burrito (not to be confused with the Beefy Fritos Burrito) was a limited-run variation of the Chili Cheese Burrito. Fitting the name, Frito-brand corn chips along with Onions were added to the base ingredients of the Chili Cheese Burrito in emulation of a Frito Pie. As the item predates wider internet adoption little information is accessible, but vague sources such as a Facebook Fan-Page[1] and personal testimonies date the item back to the mid 1990's.
