Prepare: Strain chicken, dispose of juice. In medium bowl, add chicken, Garlic Parmesan Wing Sauce and Onion Onion. Stir together until combined. Let sit in refrigerator for 30 minutes.
Serve: Break off individual lettuce leaves. Spread 1-2 tablespoons of chicken mixture over each leaf, sprinkle with mozzarella cheese and crushed nuts.
Variations: Use mini-slider rolls in place of lettuce. Serve cold or warm. Warm in oven until cheese melts. Spread onto tortilla, add lettuce and cheese and roll for a wrap version.
