This is my sister in law's recipe that she first made for us over a camp stove. I am not a big bean eater but this was AWESOME. DO NOT change anything as she told me she did & it did not turn out well. I tried tasting it without as much brown sugar & it was too vinegary. Do not obsess about how much veggies you add tho,' I added a bit more, (always trying to get more veggies in) it was still awesome!
1Use a large pot for this as it makes quite a large amount. Chop onions, peppers & halve mushrooms. Chop bacon & fry till softened but not hard cooked. If you have a LOT of bacon fat left, you could drain some off but it is best not to skimp with it. Add onions & peppers & saute till softened. Add mushrooms.
2Add the drained beans, the Chili sauce, brown sugar & cook for 2 1/2 hours in the oven at 250 degrees or on top of the stove at low heat stirring occasionally.
