DIRECTIONS
In a large skillet, cook beef and celery over medium heat until meat is no longer pink; drain. Add the soup, water, ketchup, Worcestershire sauce, mustard and pepper. Bring to a boil. Reduce heat; simmer, uncovered, for 20-25 minutes or until thickened, stirring occasionally. Spread cut sides of buns with butter; toast the buns. Top with beef mixture. Yield: 4 servings.
