In a large mixing bowl, whisk together the mayonnaise, sour cream, fresh lemon juice, dill, Dijon mustard, garlic salt, and pepper until wonderfully smooth and well combined.
Gently add the chopped cooked chicken, crisp celery, minced red onion, and toasted walnuts into the same bowl.
Mix everything thoroughly until all the chicken is beautifully coated with the creamy, flavorful dressing.
Serve this delightful salad over a bed of fresh greens, tucked into a crisp lettuce wrap with tomato slices, or on your favorite keto-friendly bread.
Keep any leftovers fresh by storing them in an airtight container in the refrigerator for several days.
