Prepare the Chicken:
Cook and cool your chicken breasts (boiled, baked, or grilled), then dice or shred them.
Make the Dressing:
In a large bowl, whisk together Greek yogurt, Dijon mustard, lemon juice, garlic powder, salt, and pepper.
Add the Veggies:
Stir in celery, red onion, and pickles for that crisp texture.
Combine Everything:
Add the chicken and mix until evenly coated. Taste and adjust seasonings if needed.
Chill Before Serving:
Refrigerate for 30 minutes for best flavor. Serve cold on greens, bread, or as a wrap.
