The Chili Cheese Burrito (initially introduced as the Chilito) is a normal sized burrito filled with cheddar cheese and a special hot chili sauce containing beef. The sauce is not topical; the beef is mixed with the sauce beforehand, making it impossible to order a Chicken or Steak Chilito. This burrito is steamed before serving.
The "Chilito" was introduced in 1990 as a part of the ¢59/79/99 budget menu. It was one of two offerings in the ¢79 category—the other being the MexiMelt. By the mid 90s, the Chilito had been removed from the National menu.
The Chili Cheese Burrito was not fully discontinued, however. Rather than removing it completely, it was instead left to franchisees to decide whether to continue carrying it, a decision that is usually decided by its relative regional popularity.
Today, the Chili Cheese Burrito is widely available throughout the Midwest of the United States, but has very limited availability West of the Rockies and East of the Appalachians. A community-sourced, complete map of all locations where Chili Cheese Burritos are available can be found here.
