In a large mixing bowl, combine the shredded cooked chicken with the BBQ sauce. Stir well until the chicken is evenly coated with the sauce. Set this mixture aside to let the flavors meld.
In a separate bowl, prepare the coleslaw by combining the coleslaw mix with the finely chopped cilantro. Add the apple cider vinegar, sugar, and a pinch of salt and pepper. Toss everything together until the cabbage and carrots are well-dressed and the mixture is combined evenly.
On a clean surface, lay out a tortilla flat. Place a generous scoop of the BBQ chicken mixture in the center of the tortilla to create the filling.
Top the BBQ chicken with a scoop of the prepared coleslaw. Arrange a few slices of avocado on top, and if desired, add pickled jalapeños for an extra kick.
Carefully fold the sides of the tortilla inward, then roll it from the bottom upwards, ensuring that the filling is securely tucked inside as you create a wrap. Repeat this process with the remaining tortillas and filling ingredients.
(Optional) For an extra layer of flavor and crunch, you can grill each wrap in a non-stick skillet over medium heat for 2-3 minutes on each side, or until they are golden brown and crispy.
Once all wraps are prepared, slice each one in half diagonally. Serve with extra BBQ sauce on the side for dipping, allowing everyone to add a little more flavor as they enjoy their wraps.
