I do it all in a big pot...first cook the bacon (I chop it first) med-hi, drain excess fat (if you want), then sauté the garlic for 30 seconds, add a whole chopped onion and green pepper, sauté together until onion just starts to get transparent. I move it to one side of the pot, and drop the meet on the other to brown it, then after getting a quick seer, mix it all together, add chili powder, cumin, salt, tomatoes, tomato paste, beans, and 1/2 a beer. Bring to slow boil then simmer for 2 hrs (stirring occasionally).
Med-high the entire time until simmer on low.
