I did this in a crockpot and have it on my short list of things to try the next time I take my Dutch oven on a camping trip. Basically just adding things, not a lot of chopping or prep work. You can pre-chop the onions at home.
From @chefhoo at thesabre.com. Also great using chicken thighs!
Sear boneless country ribs in a pan, using a rub of salt, pepper, cumin, chili powder, garlic powder, paprika and onion powder. Once brown, add chopped onions, peppers, garlic and jalepenos to the pan and sauté until the onions are clear.
Scrape the bottom until all of the brown bits disappear. Add the veggies and meat to the crockpot with a can of drained corn, one can of black beans(drained), one can of diced tomatoes, one can of plain tomato sauce, and one can of red enchilada sauce. Add more cumin, chili powder, salt and pepper as needed.
Put in the crock pot for 4 hours. Let it cool in the crock pot for at least an hour or overnight. This will help the meat absorb the sauce and make it succulent...it's one of the secrets of any braised meat or crockpot dish using big chunks of meat. Meat that is cooked in liquid still dries out the same amount as it does when it's cooked dry! It needs time to cool in the liquid!
Serve over rice with shredded cheese on top. I make this all the time...it's awesome! You can just put everything in the crock pot and skip the pan searing part, but you will lose a lot of flavor.
