Tips and Tricks
Keep the lettuce dry - After washing the lettuce, dry the leaves thoroughly. Extra water can make the wraps slippery and dilute the filling.Chop the filling fairly small - Smaller pieces of chicken, celery, walnuts, and onion make the wraps easier to fill and eat.Toast the walnuts - For a deeper nutty flavor, lightly toast the walnuts and let them cool completely before adding them to the chicken.Wait to assemble - If you're making these ahead, keep the chicken mixture and lettuce in separate containers until serving.
Storing and Reheating
Refrigerator - Store the chicken salad in an airtight container in the refrigerator for up to 3 to 4 days. Keep the lettuce leaves in a separate container so they stay crisp.Reheating - These wraps are meant to be served cold, so reheating isn't necessary.
