"You can make and bake this saucy dish in less than an hour. 'The Italian sausage really makes it a treat,' remarks Mary Detweiler of West Farmington, Ohio. 'I sometimes serve it over noodles for a complete meal.'"
In a large bowl, combine the spaghetti sauce, sausage, beans and mushrooms; mix well. Transfer to a greased 13-in. x 9-in. x 2-in. baking dish; sprinkle with mozzarella cheese. Bake, uncovered, at 350 degrees F for 40-45 minutes or until cheese is melted.
