Prep the chicken. Use well-chilled, cooked chicken for the best texture. Chop it into small pieces or shred it, then pat dry with a paper towel if it’s moist.
You want the dressing to cling, not get watered down.
Make the dressing. In a large bowl, whisk together Greek yogurt, mayo, Dijon, lemon juice, a pinch of salt, and black pepper. Add garlic powder if using. The mix should be creamy but not runny.
Add the crunch. Stir in celery, onion or scallions, and nuts if using.
Taste and adjust salt, pepper, and lemon.
Fold in the chicken and herbs. Add the chicken and fresh parsley or dill. Mix gently until everything is evenly coated. If it feels dry, add a spoonful more yogurt or a drizzle of olive oil.
Chill briefly (optional but great). Cover and refrigerate for 20–30 minutes.
This helps the flavors settle and the salad firm up.
Assemble the wraps. Lay out clean, dry lettuce leaves. Spoon 2–3 tablespoons of chicken salad into each leaf. Don’t overfill—two smaller wraps beat one messy one.
Finish with extras. Add a squeeze of lemon, a crack of pepper, or a sprinkle of paprika.
Fold and eat right away for the best crunch.
