Instructions
In a medium bowl, whisk together pineapple juice, soy sauce, brown sugar, ketchup, apple cider vinegar, garlic, ginger, black pepper, and sesame oil to create the marinade.
Place the chicken breasts in a large resealable bag or shallow dish, then pour the marinade over the chicken. Seal the bag or cover the dish and refrigerate for at least 2 hours, preferably overnight for best flavor.
Preheat your grill to medium-high heat.
Remove the chicken from the marinade, reserving the marinade for later use.
Grill the chicken for about 6-7 minutes on each side, or until fully cooked and internal temperature reaches 165°F (75°C).
While the chicken is grilling, pour the reserved marinade into a saucepan and bring to a boil.
Reduce the heat and let it simmer for about 5 minutes, then stir in the cornstarch mixture to thicken the sauce. Cook for an additional 2-3 minutes until slightly thickened.
Once the chicken is done, brush it with the thickened BBQ sauce and let it rest for a few minutes.
Slice the chicken and serve it on a platter, drizzling any remaining sauce over it. Garnish with fresh cilantro and grilled pineapple rings if desired.
