Place the Italian sausage links, spaghetti sauce, green pepper and onion into a slow cooker. Stir to coat everything in sauce. Cover, and cook on Low for 6 hours. Serve on hoagie rolls.
Other sources say that you can keep the fresh cooked sausage in the refrigerator up to seven days if kept at 40 degrees F (which is the normal setting in both restaurant and home refrigerators). Another says up to five days for cooked Italian sausage, lightly smoked sausage, or breakfast sausage.
