Place chicken breast on a foil lined baking sheet. Sprinkle both sides of chicken breasts with ¼ tsp salt and black pepper. Pour ¼ cup of the BBQ sauce on both pieces of the chicken. Spread the BBQ sauce around on both sides. Bake for 25 minutes or until the internal temperature is 165°. Allow to cool and chop into cubes.
Preheat oven to 425°.
Split each baked potato in half. Season each potato liberally with salt and pepper. Run a fork through the insides to break it up and mix the salt and pepper throughout. Divide the chicken between all 8 halves of the potatoes. Top each potato half with 1 tbsp of BBQ sauce, red onion and cheese. Place them on a foil lined baking sheet.
Bake the potatoes for 5-7 minutes or until the cheese is melted. Top with sour cream and cilantro. Serve.
