Caribbean Beef Salad with Mango

Dressing:
8 oz plain low fat yogurt
1/4 cup sour cream
1/3 cup chopped Mango Chutney
2 tbsp apple cider vinegar
1 tbsp lemon juice
1/8 tsp ground allspice
1/8 tsp freshly ground black pepper

Salad:
1 lb deli roast beef cut into ¼" slices
4 cups torn romaine lettuce leaves
1 large mango peeled and cut into ¾" cubes
1 red bell pepper cut into ¾" pieces

To make the dressing, combine the yogurt, sour cream, chutney, vinegar, lemon juice, allspice, and pepper in a medium bowl. Trim the fat from the roast beef.
Stack the beef slices and cut lengthwise in half and then crosswise into ½-inch-wide strips. To serve, put the lettuce on a serving platter and arrange the beef, mango, and bell pepper on top of the lettuce.
Drizzle ½ cup dressing over the salad and pass the remaining dressing separately.
