Combine seasoned chicken, grapes, celery (if used) and pecans in a large bowl, set aside.
Mix mayonnaise, sour cream, honey and poppy seeds in a small bowl to blend. Add to chicken mixture.
Toss well to coat. Serve over lettuce, or with your favorite bread or crackers.
Note: the original recipe doesn't call for celery. I add it when I want to change the taste up a bit and add a little more crunch. It's equally delicious either way. Another variation is to use dried cranberries in place of the grapes.
