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.

Add corn to the water in the last 10 minutes of cooking time, if desired, and shrimp or craw fish in the last three minutes of boiling time, if desired to create a southern-style boil.
