Heat the soup and Worcestershire in a 2-quart saucepan over medium-high heat to a boil. Add the beef and heat through, stirring occasionally.
Divide the beef evenly among the rolls. Top the beef with the cheese slices and place the sandwiches onto a baking sheet.
Bake for 3 minutes or until the sandwiches are toasted and the cheese is melted. Spoon the soup mixture onto the sandwiches. Top each sandwich with 1 tablespoon pepper rings.
