Petros Chili&chips

The Petro® made its debut at the 1982 Worlds Fair in Knoxville, Tennessee. Originally served in a sliced open Fritos® bag and piled high with chili and mounds of toppings, it was an instant hit with fair-goers. To tie in with the energy theme of the Worlds Fair,the Petro® was initially dubbed a Petroleum Belly, then shortened to Petro® and used other energy related terms like Regular Petro®, Premium Petro®, Unleaded Petro® (which was a bag of Fritos corn chips) and Additives like hot and mild sauces. Two years later, Petros were served in New Orleans at the 1984 World Expo. Again, it wasnt long before attendees stood in long lines awaiting their introduction to the Petro®.
