These stuffed pita chicken sandwiches make a fabulous lunch entree.

Did you know that walnuts are one of the healthiest foods you can eat?  Walnuts are the only nut that contain a significant amount of omega-3 fatty acids. No other nut even comes close.  Eating a handful of walnuts every day is one small step you can take to protect your heart.  The U.S. Food and Drug Administration even approved a qualified health claim for walnuts, the first ever for a whole food.

In a large bowl combine the spinach, yogurt, lemon juice, mustard, green onion, dill or tarragon and celery and stir to combine. Add the chicken, apple, and chopped walnuts, blend well, then season to taste with salt and pepper if you wish.

Either serve the salad on a bed of lettuce leaves, or spoon about 1/2 cup of it into each pita half, tuck in a lettuce leaf, and serve.
