answer:You would most likely have to rent or borrow some outdoor style restaurant quality cooking stoves and pots. I don’t think you could adequately make enough on a camp stove with your own pots, however, maybe someone you know has some really big pots, and if you had more than one camp stove, you could use several large (but not industrial size) pots. However, as I’m looking around on the web, I came across This Picture of a firefighter’s chili cookoff. It looks like the big portable turkey roasting pan my mom uses at Thanksgiving. Maybe that could work. I think you’d have to do most of the cooking at home, ahead of time, then tote the beans in big tupperware containers to the venue, then simply heat it up in the roasting pan, or on big pots over multiple camp stoves, just make sure the stoves are big enough to accommodate big pots. Have they ever had any chili cook offs in your town? If so, maybe you could contact the people who participated to see what types of equipment they used and where they got the stuff.
