In a medium bowl, combine shredded chicken and BBQ sauce. Stir until chicken is well coated. Set aside.
In another bowl, prepare coleslaw by mixing coleslaw mix, mayonnaise, apple cider vinegar, sugar, salt, and pepper. Stir until well combined.
Optional: Add chopped cilantro and sliced green onions to coleslaw. Stir to incorporate.
Let coleslaw rest for 10 minutes to allow flavors to meld and cabbage to soften slightly.
Warm flour tortillas in microwave for 15 seconds or in dry skillet for 10 seconds per side.
Lay one tortilla flat. Place generous portion of BBQ chicken mixture in center, followed by heaping scoop of coleslaw.
Fold sides of tortilla over filling, then roll tightly from bottom to enclose filling completely.
Repeat with remaining tortillas and filling. Cut each wrap in half diagonally and serve immediately.
