Grilled Chicken Citrus Salad

This is a wonderful refreshing summer recipe. Very good! A must try.

Ingredients:
 1/2 cup orange juice
 1/4 cup lime juice
 2 shallots, minced
 2 cloves garlic, minced
 1 teaspoon chili powder
 1 teaspoon ground cumin
 1 teaspoon white sugar
 4 (4 ounce) skinless, boneless chicken breast halves
 8 cups torn romaine lettuce
 2 oranges - peeled, segmented, and chopped
 2 stalks celery, sliced
 4 green onions, chopped

Directions:
In a mixing bowl, whisk together orange juice, lime juice, shallots, garlic, chili powder, cumin, and sugar. Pour 1/2 of this mixture into a large, resealable plastic bag, and add the chicken breasts. Seal, and refrigerate for at least 2 hours. Refrigerate the remaining dressing.
Preheat an outdoor grill for medium-high heat. In a large salad bowl, toss romaine lettuce with oranges, celery, and green onions. Set aside.
Lightly oil grate, and place chicken on grill. Discard the marinade from the chicken. Cook for 6 to 8 minutes each side, or until juices run clear when pierced with a fork. Remove chicken from grill, and slice into thin strips.
Toss salad with reserved dressing, and top with sliced chicken.
