This quick and simple roast beef wrap really packs in the flavor thanks to a zesty horseradish sauce.
1) Stir together mayo, mustard, and horseradish and spread the sauce on a large flour tortilla.
2) Add roast beef to the tortilla and top with cheese. Top with arugula and a few sprouts.
3) Fold ends over the wrap and roll it into a tight wrap.
4) Cut wrap in half and keep cold until lunch!
