Instructions:
In a large mixing bowl, toss together all ingredients except for the roast beef, until well combined.
Cover with plastic wrap and let stand in the refrigerator for 30 minutes.
Lay the roast beef slices out flat on a work surface. Place 2 tablespoons of the cole slaw in the center of each slice and roll up.
For a unique presentation, stand up on a tray or incorporate into a party platter garnished with potato salad and bunches of fresh parsley.
