Start by gathering all your ingredients. If you haven't already, shred your cooked chicken and dice the celery and onion. If you're using frozen peas, make sure they are thawed and drained.
In a large mixing bowl, combine the shredded chicken, mayonnaise, and prepared pesto. Stir until the chicken is well coated with the creamy mixture.
Next, fold in the diced celery, sweet green peas, and finely diced onion. This is where the salad starts to come alive with color and texture.
Sprinkle in the shredded Parmesan cheese and gently mix to incorporate. The cheese adds a wonderful salty flavor that complements the pesto beautifully.
You can serve the Pesto Chicken Salad immediately, or for enhanced flavors, cover it and let it chill in the refrigerator for about 30 minutes before serving. This allows the flavors to meld beautifully.
When ready to serve, dish out the salad onto plates or into bowls. Garnish with a sprinkle of pine nuts for added crunch and a little extra Parmesan cheese on top for a touch of elegance.
