Assemble the ingredients. Crumble and brown the sausage in a medium size skillet; drain grease and set aside.
Cut the kielbasa (or turkey sausage) at a diagonal into 1-inch pieces. Set aside.
Chop the onions and green bell pepper. Measure the ketchup and the brown sugar.
Spray the inside of a 6 or 7-quart crockpot with no stick cooking spray.
Place the sausage and kielbasa in crockpot. Dump the cans of beans, seasonings, and tomatoes into the crockpot.
Add the brown sugar, onions, ketchup, and green peppers. Stir all of the ingredients together until well combined.
Cook on low, uncovered, for 5 hours. Stir the bean mixture occasionally.
Serve warm from the crockpot as a side or add cornbread and serve as a meal.
