Step 1: Combine the Chicken and Vegetables: In a medium-sized bowl, gently combine the diced cooked chicken, chopped celery, red onion, and fresh parsley. Ensure that the ingredients are evenly distributed for a balanced flavor in each bite.
Step 2: Prepare the Dressing: In a separate small bowl, whisk together the Greek yogurt, Dijon mustard, lemon juice, olive oil, salt, and pepper until smooth and well combined. Taste and adjust seasonings as needed to achieve the desired flavor profile. A touch more lemon juice can brighten the dressing, while additional mustard adds a savory depth.
Step 3: Dress the Salad: Pour the dressing over the chicken and vegetable mixture. Gently fold the ingredients together until everything is evenly coated with the dressing. Be careful not to overmix, as this can cause the chicken to become shredded.
Step 4: Add Optional Ingredients (if using): If desired, add the dried cranberries or grapes and chopped walnuts or almonds to the salad. Gently fold them in to distribute them evenly throughout the mixture. These additions provide a delightful textural contrast and a burst of sweetness and nuttiness.
Step 5: Chill and Serve: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld together. This step is crucial for enhancing the overall taste of the salad. Serve chilled on a bed of lettuce, in a sandwich or wrap, or with crackers.
For a spicier kick, add a pinch of red pepper flakes to the dressing. To make it dairy-free, substitute the Greek yogurt with avocado or a dairy-free yogurt alternative. Different herbs like dill or chives can be used instead of parsley for a varied flavor.
