Step 1: If using raw chicken, cook it by boiling, poaching, or roasting until fully cooked. Allow it to cool completely, then dice or shred.

Step 2: In a large bowl, add cooked chicken, halved grapes, chopped celery, and onion.

Step 3: In a small bowl, mix mayonnaise, lemon juice, salt, and black pepper.

Step 4: Pour the dressing over the chicken mixture and gently fold until evenly coated.

Step 5: Taste and adjust seasoning as needed. Refrigerate for 20–30 minutes before serving for best flavor.
