Elmer Doolin was so taken with the bag of corn chips served with his lunch in San Antonio, Texas that he paid $100 for the recipe. In 1932, he started the Frito Corporation. Original Fritos ingredients are limited to whole corn, corn oil, and salt. Even today, Fritos (original and barbecue flavor) are a vegan snack. This is how your lunch snack came into being. I like them better than regular potato chips.
