I've lived in San Antonio and my g/f lives there so I still spend a lot of time there. I also like beans in chili when I make it with ground beef with HEB or McCormick's Chili mix. I also add a can of Rotel Diced tomatoes, onion and sometime a can of corn. If I'm really hungry and feeling poor I mix it with rice.It spread through cattle drives, it originated in San Antonio with the Spanish and canary islanders. Beans were a side dish.
I haven't had chili with cubed sirloin w/out beans in a long time but it's damn good too.
