In a large mixing bowl, combine cooked chicken, crispy diced bacon, halved cherry tomatoes, diced red onion, and diced celery. Stir gently until well mixed.

In a separate small bowl, whisk together mayonnaise, lemon juice, salt, garlic powder, onion powder, and black pepper until smooth and creamy.

Pour the dressing over the chicken salad mixture and gently fold the dressing into the salad until all ingredients are coated.

Taste the salad and adjust seasoning with additional salt, pepper, or lemon juice, if necessary.

Serve the salad immediately or chill in the refrigerator for about 30 minutes for enhanced flavors.
