Set your crock pot to low and add beans, tomato soup, water, onion and seasonings. Cook for one hour.
Over medium high heat brown sausage in small skillet. Drain fat and place sausage on a plate that has been layered with paper towels. Let more grease get absorbed in paper towels than add sausage to the crock pot. Also add the potatoes and green pepper at this time. Continue to cook on low for 8 hours or until potatoes are tender.
