Chris and I really love this sandwich, it is so good that you will think there is no way this can be healthy. It makes for a great lunch that can be prepared ahead.
One package of boneless, chicken breast
1 handful of red grapes, halved
2 ribs of celery, finely chopped
1/4 c. red onion, chopped
1 teaspoon dried tarragon
1/4 c. toasted walnuts, chopped
1/2 c. of fat free mayo
1/4 c. fat free plain yogurt
Boil the chicken in low sodium, low fat chicken broth until center is no longer pink, around 30 minutes depending on the thickness. When the chicken is cool enough to touch, either shred or cut into small cubes, whatever you want to do is fine. Let the chicken cool in fridge, you don't want to put mayo on warm chicken. While the chicken is in the fridge chop your onions and celery put into large mixing bowl. Add halved grapes, tarragon, yogurt, and mayo. Mix together and add cold cooked chicken. Add the walnuts just before you eat the salad otherwise they will lose their crunch.
This can be made into a sandwich, a salad by adding lettuce (my favorite is butter lettuce), or using pita chips to scoop up the chicken mixture.
This is about 4-6 servings depending on the amount.
