Step 1: Prepare the Chicken: Ensure the chicken is fully cooked and cooled. Dice the chicken into bite-sized pieces. This can be from a roasted chicken, poached chicken breasts, or even leftover grilled chicken.
Step 2: Dice the Apple, Celery, and Onion: Dice the apple (no need to peel, unless preferred) and celery into small, uniform pieces to ensure an even distribution of flavor and texture. Finely dice the red onion.
Step 3: Combine Ingredients: In a large bowl, gently combine the diced chicken, apple, celery, and red onion.
Step 4: Make the Dressing: In a separate small bowl, whisk together the mayonnaise, Greek yogurt (if using), and lemon juice until smooth. Season with salt and pepper to taste.
Step 5: Dress the Salad: Pour the dressing over the chicken and apple mixture. Gently fold to combine, ensuring all ingredients are evenly coated. Be careful not to overmix, as this can make the chicken salad mushy.
Step 6: Add Nuts and Herbs (Optional): If desired, add the chopped walnuts or pecans and fresh parsley. Gently fold to incorporate.
Step 7: Chill and Serve: Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. Serve chilled on croissants, lettuce wraps, or with crackers.
For a tangier flavor, a teaspoon of Dijon mustard can be added to the dressing. For a spicier kick, add a pinch of cayenne pepper. If apples aren't preferred, pears make a great substitute. For a crunchier texture, toast the nuts before adding them.
