Pull the breast meat off your Costco rotisserie chicken and shred it into bite-size pieces using two forks or your hands. You'll want around 1 ½ cups of shredded meat, which usually comes from just one breast.
Place the shredded chicken into a large bowl, then add about 6 cups of the lettuce and cheese mixture from your Caesar kit, which is roughly half the bag. Toss everything together so the chicken gets distributed evenly through the greens.
Drizzle in the Caesar dressing pouch along with the croutons from the kit. Squeeze the juice from the lemon wedge over the top for a little extra brightness, then toss everything until it's well coated.
Scoop a heaping ½ cup of the chicken Caesar mixture into the center of a mini naan or tortilla. Fold it over like a taco, tucking the filling in so it doesn't spill out the sides.
These wraps taste best eaten immediately while the lettuce is still crisp and the croutons still have their crunch. Serve them right after assembling for the best texture.
