Preheat your oven to 375°F.
In a large skillet, heat olive oil over medium heat.
Season the chicken breasts with garlic powder, onion powder, salt, and pepper.
Add the chicken to the skillet and cook for about 5-7 minutes on each side, or until fully cooked and no longer pink in the center.
Remove from heat and shred the chicken using two forks.
In a mixing bowl, combine the shredded chicken with BBQ sauce, stirring until the chicken is well coated.
Place the slider buns on a baking sheet and spoon the BBQ chicken mixture evenly onto the bottom halves of the buns.
In another bowl, mix the coleslaw mix, mayonnaise, apple cider vinegar, and sugar until well combined.
Spoon the coleslaw over the BBQ chicken on each slider.
Place the top halves of the buns on each slider.
Bake in the preheated oven for about 10 minutes, or until the buns are slightly toasted.
Remove from the oven and serve warm.
