Preparation

In a small saucepan, bring the barbecue sauce and scallion to a simmer. Stir in the beef and bring to a bare simmer. Cover, remove from the heat, and set aside. In a medium bowl, stir together the sour cream, mayonnaise, horseradish, vinegar, honey, and pepper sauce until blended. Toss in the coleslaw until evenly coated with the dressing. Open up the rolls and spoon the beef mixture on the roll bottoms, dividing evenly. Spoon the slaw over the beef, dividing evenly, and cover with the roll tops. Serve with additional barbecue sauce, if you wish.
