In a large mixing bowl, combine the basil pesto, Greek yogurt, and fresh lemon juice. Stir until well blended to create a creamy dressing.
Add the shredded rotisserie chicken to the bowl and toss until fully coated with the pesto dressing.
Fold in the cherry tomatoes, cucumber, and red onion. Mix gently to combine all the ingredients evenly.
Season the salad with salt and pepper to taste. Optionally, sprinkle toasted pine nuts on top for added crunch and flavor.
Serve the pesto chicken salad over a bed of mixed greens or spinach for a nutritious meal.
Notes
You can substitute rotisserie chicken with grilled chicken or leftover roasted chicken. For a dairy-free option, replace Greek yogurt with a dairy-free alternative.
