Mix all ingredients together except the wraps. I use about 1/3 cup chicken per wrap and the other ingredients are to taste/desired level. I tear the larger pieces of lettuce into smaller pieces.
Place chicken mixture onto wrap and fold. Cut wrap in half.
Serve immediately or wrap in plastic wrap for later
Notes
I think mixing the ingredients together works better than layering as you get everything in every bite and the dressing throughout. However, you can certainly layer if you want.
