Italian Sausage Stuffing

Heat 10-inch skillet over medium-high heat until hot. Add sausage and cook until browned, about 10 minutes, stirring frequently to break up sausage. With slotted spoon, transfer sausage to large bowl; stir in stuffing mix. To drippings in skillet, add margarine or butter; heat until melted. Add celery and onion and cook, stirring occasionally, until vegetables are tender and golden, about 10 minutes. Transfer celery mixture to bowl with sausage. Pour 2 1/2 cups hot water over stuffing mixture; toss to mix well. Spoon stuffing into 13" by 9" glass baking dish; cover with foil and bake in preheated 325 degrees F oven 30 minutes or until stuffing is heated through.
