Place the chicken breasts in a pan and cover with broth. Bring to a simmer and cook until done, about 8 to 10 minutes. Allow to cool in the broth, then cut into small dice.

In a small bowl mix together the mayonnaise, sour cream, orange zest, and juice. Add the dressing to the chicken. Stir in the apple and celery.

Place a leaf of lettuce on each of 6 slices of bread. Top with chicken salad and top with a second piece of bread. Refrigerate wrapped in plastic wrap, until ready to serve. Cut each sandwich in half.
