Spinach-Stuffed Shells

Directions

1. In a large skillet, cook beef and onion over medium heat until meat is no longer pink. Remove from the heat. Stir in the spinach, cottage cheese, Parmesan cheese, carrot and seasonings; mix well. Stuff into pasta shells. Arrange in a greased 13x9-in. baking dish; set aside. In a saucepan, melt butter; stir in flour until smooth. Gradually add milk and salt; bring to a boil. Cook and stir for 2 minutes or until thickened. Pour over shells; sprinkle with mozzarella cheese. Cover and bake at 350° for 30 minutes or until heated through. Uncover and bake 5 minutes longer or until browned.
