This is a very easy recipe to make, but so delicous! I have brought this to potlucks and always come home with an empty dish and many requests for the recipe. Even people that aren't a fan of zucchini have liked it!
Preheat oven to 350*. Lightly grease a 3 quart rectangular baking dish; set aside. In a 12 inch skillet, cook sausage over med. heat until brown; drain off fat. Return sausage to skillet.
Meanwhile, halve zucchini lenghtwise; cut crosswise into 1/4 inch peices. Add zucchini to sausage in skillet. In a small bowl, combine soup and sour cream; stir into sausage mixture. In a large bowl, combine stufffing mix and melted butter.
Spoon half of the stuffing mixture into the prepared baking dish. Spread sausage mixture over stuffing in dish. Spoon remaining stuffing mixture evenly over sausage mixture. Bake, covered, about 30 minutes or until heated through.
