In a nonstick skillet, cook the beef, onion and green pepper over medium heat for 4-5 minutes or until meat is no longer pink; drain.

Stir in the ketchup, vinegar, brown sugar and mustard. Bring to a boil. Reduce heat; simmer, uncovered, for 5-7 minutes or until thickened. Spoon onto roll bottoms; top with coleslaw. Replace roll tops. Yield: 2 servings.
