Cook pasta according to package directions. Meanwhile, in a large skillet, cook beef over medium heat until no longer pink; drain and set aside.
In the same skillet, cook bacon until crisp; remove with a slotted spoon to paper towels. Discard drippings. Drain pasta; add to the skillet. Stir in the soup, beef and bacon; heat through. Sprinkle with cheese; cover and cook until the cheese is melted. Serve with barbecue sauce and mustard if desired.
