In a large mixing bowl, combine the shredded chicken, pesto, Greek yogurt, and mayonnaise. Use a spatula to mix thoroughly until the chicken is evenly coated with the creamy dressing.
Next, add the halved cherry tomatoes, diced cucumber, finely chopped red onion, and roughly chopped walnuts to the bowl. Carefully fold the ingredients together with a gentle hand to maintain the integrity of the tomatoes and cucumber, avoiding any mashing.
Season the salad with salt and pepper according to your preference. Taste and adjust the seasoning to achieve the desired flavor balance.
Once seasoned, cover the bowl with plastic wrap or a lid and refrigerate for at least 30 minutes. This chilling period allows the flavors to meld together, enhancing both creaminess and taste.
When you are ready to serve, give the salad a gentle stir to re-mix the ingredients. Transfer the salad to a vibrant serving platter or scoop into individual bowls for a personal touch.
Lastly, garnish with fresh basil leaves, adding a pop of color and a refreshing burst of flavor that complements the salad beautifully.
Notes
For an appealing presentation, serve in a clear bowl and sprinkle additional walnuts on top.
