Make the slaw: Toss the coleslaw mix, dill, vinegar, sugar, mayonnaise, sour cream, horseradish, 3/4 teaspoon salt, and pepper to taste in a bowl.
Layer the cheese, roast beef and slaw in the center of the wraps. Fold in the sides, then roll up tightly. Cut in half and serve with chips, if desired.
