In a large mixing bowl, combine diced chicken, grapes and celery.
Prepare dressing: In a small bowl, whisk together all dressing ingredients (mayonnaise, apple cider vinegar, honey, poppy seeds and seasoning).
Pour dressing over chicken mixture, toss until salad is evenly coated. Cover and chill for 1 hour before serving. Adjust seasoning to taste preference.
Notes
Note: If you are using a rotisserie chicken that is salty, you may want to omit the salt.
