In a medium bowl, combine the shredded chicken and Korean BBQ sauce. Mix well until the chicken is evenly coated.
Heat a skillet over medium heat. Add the chicken mixture and cook for about 5-7 minutes, stirring occasionally, until heated through.
While the chicken is heating, warm the corn tortillas in a separate skillet or in the microwave until pliable.
To assemble the tacos, place a generous amount of the BBQ chicken on each tortilla.
Top the chicken with shredded cabbage, diced cucumbers, green onions, and cilantro.
Sprinkle sesame seeds over the top and serve with lime wedges on the side.
