Bake crescent rolls as directed on can.
Two minutes before rolls are done baking, add beef strips to broth; cook 2 minutes. Remove from heat.
With serrated knife, split crescent rolls. With tongs, remove beef from broth; fill each crescent roll with beef. Serve sandwiches with remaining broth for dipping.
