I culled this recipe from "Semi Homemade with Sandra Lee"...and then I later saw Ina Garten make this same recipe. As usual I tweak it a bit when I make it.
1/2 c mayonnaise
1/4 c plain yogurt
1 tsp. poppy seeds
1 tsp. tarragon, finely chopped
14 oz. cooked chicken, cubed
1 c seedless grapes, halved
2 celery ribs, chopped
1/4 c chopped nuts
salad mix, bread, etc.
Combine first 4 ingredients to make dressing. Combine 1/4 c of the dressing with the salad mix. Combine remaining ingredients and then combine with 1/2 of remaining salad dressing. Serve chicken mixture atop salad greens and add more dressing as desired.
I generally dump all the ingredients in a bowl except for the salad and bread, and then mix everything together and put it in a pita pocket with the salad greens. I couldn't find fresh tarragon so I used dried. I also tend to eyeball all the ingredients. I know I used more poppy seeds and tarragon than what the recipe calls for. I tend to boil up my own chicken for this, Sandra Lee started with an already cooked rotisserie chicken...I don't remember what Ina did.
