In a large bowl or zip-top bag, blend brown sugar, ketchup, pineapple juice, soy sauce, Worcestershire sauce, apple cider vinegar, ground ginger, minced garlic, paprika, black pepper, sriracha if desired, and toasted sesame oil. Mix thoroughly until sugar dissolves and mixture is homogenous. Reserve 1/2 cup marinade in a separate bowl to use for glazing during grilling.

Add chicken thighs to the remaining marinade, ensuring every piece is completely coated. Seal and refrigerate for 4 to 6 hours, or overnight for optimal flavor absorption. Remove from the refrigerator 20 to 30 minutes before grilling and let stand at room temperature.

Preheat a grill to medium-high heat (400–425°F). Lightly oil the grates with vegetable oil using tongs and a folded paper towel to prevent sticking. While the grill heats, cut the pineapple into 1-inch thick rounds and prepare for grilling.

Place marinated chicken thighs on the hot grill. Sear undisturbed for 6 minutes until a caramelized crust forms. Flip and grill for another 3 minutes on the opposite side.

Flip the chicken again and brush generously with the reserved glaze. Grill for 1 to 2 minutes, flip once more, brush with additional glaze, and cook another 1 to 2 minutes until internal temperature reaches 165°F.

Remove chicken from grill and let rest on a clean cutting board or plate for 10 minutes to allow juices to redistribute.

While chicken rests, grill pineapple rounds for 3 to 4 minutes per side until caramelized and marked by the grill.
