In a small mixing bowl, add the Greek yogurt, Dijon mustard, honey, apple cider vinegar, garlic powder, salt, and black pepper.
Using a wire whisk, mix until smooth.
In a large mixing bowl, add the chicken, apple, cheddar cheese, celery, and red onion.
Add the dressing to the chicken mixture. Stir until the ingredients are evenly coated.
Place 2 lettuce leaves on each serving plate. Divide the chicken mixture evenly among the lettuce leaves. Sprinkle the chopped pecans over the filling, if using.
Serve immediately.
Notes
Tips and Tricks
Use a crisp apple - Softer apples can become mushy once mixed with the dressing. Firm varieties hold their texture better.Dice the filling evenly - Smaller, similarly sized pieces of chicken, apple, celery, and onion make the lettuce wraps easier to eat.Keep the lettuce dry - Pat the leaves dry after washing so the filling doesn’t slide around or become watery.Add pecans just before serving - This keeps them crunchy instead of letting them soften in the dressing.
Storing
Store the filling separately - Place the chicken mixture in an airtight container in the refrigerator for up to 3 days.Store the lettuce on its own - Keep washed and dried lettuce leaves in a separate container lined with a paper towel to help them stay crisp.Assemble before serving - Fill the lettuce leaves shortly before eating so they don’t become soft from the dressing.
