Pinto beans (frijoles), a staple of Tex-Mex cooking, have long been associated with chili and the question of whether beans "belong" in chili has been a matter of contention amongst chili cooks for an equally long time. It is likely that in many poorer areas of San Antonio and other places associated with the origins of chili, beans were used rather than meat or in addition to meat due to poverty. In that regard, it has been suggested by some chili aficionados that there were probably two chili types made in the world, depending on what could be afforded and how frugal the cook was.
As chili spread east into areas where beef was more expensive (beef was plentiful and cheap in San Antonio and other cattle towns), chili with Pinto or other beans became more prevalent. In some eastern areas, this dish is referred to as "chili beans" while the term chili is reserved for the all-meat dish. Other changes included the adding of other vegetables. Tomatoes are almost always used, bell peppers are common and even celery appears in recipes. Many easterners are just as adamant about the inclusion of beans in their chili for an authentic flavor as Texans are about their exclusion.
Most commercially prepared canned chili includes beans. Commercial chili prepared without beans is usually called "Chili No Beans". A vocal minority of self-styled 'chili experts' believe that beans and chili should always be cooked separately and served on the side. It is then up to the consumer to stir his preferred quantity of beans into his own bowl. Some cooks prefer black beans, black-eyed peas, or kidney beans instead of pinto beans.
A popular saying among self-proclaimed chili purists is "If you know beans about chili, you know chili ain't got no beans". The thought that beans do not belong in chili may be further credited to the fact that most ?official? chili cook-offs do not allow beans. In many cases a chili will be disqualified if it contains such ingredients considered ?filler?. Article I, A, 2 of the CASI rules states: "2. NO FILLERS IN CHILI - Beans, macaroni, rice, hominy, or other similar ingredients are not permitted."
