Step 1: Prepare the chicken
Shred or dice the cooked chicken into bite-sized pieces. Rotisserie chicken, poached chicken breasts, or roasted chicken all work well for this recipe.
Step 2: Mix the dressing
In a large mixing bowl, whisk together the mayonnaise, Dijon mustard, lemon juice, salt, and black pepper until smooth and creamy.
Step 3: Add the mix-ins
Fold in the celery, onion, grapes, nuts, and parsley. These ingredients add texture, freshness, and layers of flavor.
Step 4: Combine the salad
Add the shredded chicken to the bowl and gently mix until everything is evenly coated with the dressing. Taste and adjust seasonings if needed.
Step 5: Chill and serve
Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled on a bed of lettuce, as a sandwich filling, or with crackers for a light snack.
