Citrus Chicken Salad

In a small bowl, whisk together juices, shallots, chili powder, cumin, sugar and garlic powder.  

Pour half of this mixture into a large, resealable bag.  Add the chicken breasts.  Refrigerate for 2 hours.  Refrigerate the remaining half of dressing.

Remove chicken breasts from marinade.  Discard marinade.  Broil chicken breasts on HIGH for 4 minutes.  Turn.  Broil an additional 3 to 4 minutes or until internal temperature reaches 160 degrees.  Slice into thin slices.

Meanwhile, gently toss together remaining dressing, lettuce, oranges, onion and almonds.  Top with chicken.
