Prep the Packets: Preheat oven to 400°F (200°C) or heat grill to medium-high. Cut 4 large sheets of aluminum foil.
Season the Chicken: In a bowl, combine chicken pieces with teriyaki sauce, garlic, olive oil, salt, and pepper. Toss to coat evenly.
Assemble the Packets: Divide the chicken mixture evenly among foil sheets. Top with pineapple chunks. Fold the foil over and seal tightly to form packets.
Cook:
Oven: Place packets on a baking sheet and bake for 25–30 minutes, until chicken is fully cooked.
Grill: Cook packets directly on the grill for 20–25 minutes, turning halfway through.
Serve: Carefully open packets (watch for steam). Garnish with sliced green onions and sesame seeds before serving.
