Cut celery stalks into ¼ inch pieces. Dice red onion finely into ⅛ inch pieces. Pat celery dry with paper towel if very wet.

In a large bowl, whisk together mayonnaise, Dijon mustard, 1 tablespoon lemon juice, salt, and black pepper until smooth and combined.

Add shredded chicken, diced celery, and red onion to the dressing. Fold gently with a spatula until all pieces are evenly coated. Taste and add more lemon juice, salt, or pepper if needed.
