This recipe is adapted from one that appeared in The Whole Foods Market Cookbook published in 2002. It was sold in their Deli section of prepared foods. I don't know if they still offer it or not. I do minimal shopping at their stores and limit my purchases to specific items I can't get elsewhere at much cheaper prices. I made some minor changes to the recipe. If your are not a fan of Tarragon, omit it or substitute another herb. The original did not include Tarragon. I also poached the chicken rather baking. I added flat leaf parsley as well. I served the salad on a bed of baby spinach with cottage cheese, avocado and smoked Gouda cheese. The salad works well as a sandwich filling or stuffing for Pita Pocket bread.
