Step 1: Prepare the Chicken: Ensure the cooked chicken is diced into bite-sized pieces. This provides a consistent texture and makes it easier to mix with the other ingredients.
Step 2: Dice the Apple and Celery: Core and dice the apple into small, uniform pieces. Similarly, dice the celery into similar-sized pieces. This consistency helps create a balanced texture in the salad.
Step 3: Combine Ingredients: In a medium-sized bowl, gently combine the diced chicken, apple, celery, and red onion. Mix well to distribute the ingredients evenly.
Step 4: Prepare the Dressing: In a separate small bowl, whisk together the mayonnaise, Greek yogurt (if using), and lemon juice. Season with salt and pepper to taste. Adjust the lemon juice to achieve desired tanginess.
Step 5: Dress the Salad: Pour the dressing over the chicken and apple mixture. Gently fold the ingredients together until everything is evenly coated with the dressing. Be careful not to overmix, as this can make the salad watery.
Step 6: Add Nuts and Herbs (Optional): If desired, stir in the chopped walnuts or pecans and fresh parsley. These additions provide extra flavor and texture.
Step 7: Chill and Serve: Cover the bowl and refrigerate the apple chicken salad for at least 30 minutes to allow the flavors to meld. Serve chilled on lettuce leaves, in croissants, or with crackers.
For a sweeter salad, use a sweeter apple variety like Fuji. For a tangier salad, add a teaspoon of Dijon mustard to the dressing. If you don't have Greek yogurt, you can use all mayonnaise, but the yogurt adds a lighter touch.
