Step 1: Prepare the Chicken: If using raw chicken, cook it thoroughly until no longer pink inside (poaching, grilling, or baking are good options). Allow the chicken to cool slightly, then dice into bite-sized pieces. If using pre-cooked chicken, ensure it is ready to use.
Step 2: Combine Ingredients: In a medium-sized bowl, combine the diced chicken, diced apple, chopped celery, and diced red onion. These ingredients form the base of salad, so ensure they are evenly distributed.
Step 3: Prepare the Dressing: In a small bowl, whisk together the mayonnaise, Greek yogurt (if using), chopped fresh parsley, and lemon juice. Blend these components until smooth and well-combined. This creates a harmonious blend of creamy and tangy flavors.
Step 4: Dress the Salad: Pour the dressing over the chicken and apple mixture. Gently stir until all ingredients are evenly coated. Take care not to overmix, as this can make the salad mushy.
Step 5: Season to Taste: Add salt and pepper to taste, adjusting the seasoning as needed. The balance of flavors is crucial, so taste and adjust accordingly. Consider a pinch of cayenne for subtle heat or a touch of honey for extra sweetness, if desired.
Step 6: Chill and Serve: Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. This step is crucial for enhancing the salad's overall taste. Before serving, stir in the toasted walnuts or pecans, if using. Serve the chicken and apple salad on lettuce leaves or with croissants, if desired.
Tips and Substitutions: For a lighter salad, substitute the mayonnaise with more Greek yogurt or use a vinaigrette-based dressing. Other fruits like grapes or dried cranberries can be added for extra sweetness. Toasted almonds can be used in place of walnuts or pecans. If red onion is too strong, soak it in cold water for 10 minutes before using.
