Cook the Chicken: If not using pre-cooked chicken, cook the chicken breast in boiling water or bake in the oven until fully cooked. Allow it to cool, then shred or dice the chicken into bite-sized pieces.
Prepare the Dressing: In a mixing bowl, combine mayonnaise, sour cream, Dijon mustard, honey, garlic powder, onion powder, cayenne pepper, salt, and black pepper. Mix well until smooth and creamy.
Combine Ingredients: In a large mixing bowl, add the cooked chicken, chopped green onions, celery, red bell pepper, and jalapeños (if using). Mix gently to combine.
Add Dressing: Pour the prepared dressing over the chicken and vegetable mixture. Toss gently until all ingredients are evenly coated with the dressing.
Adjust Seasoning: Taste the chicken salad and adjust seasoning if necessary. Add more salt, pepper, or cayenne pepper according to your preference.
Chill: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld together.
Serve: Before serving, sprinkle chopped cilantro or parsley over the chicken salad. Optionally, squeeze fresh lime juice for added freshness. Serve chilled as a sandwich filling, on a bed of lettuce, or with crackers.
