Method
Remove chicken from bone then chop and add to a large bowl with onion, celery, and scallions.
In a small bowl, whisk zest, juice, honey, mayo, salt/pepper, poppy seeds, and mustard until smooth.
Add dressing to chicken mixture and stir until well combined.
Fold in nuts and cranberries.
Garnish with scallions.
Notes
If you're not a fan of mayo, you can use plain Greek yogurt instead.
