Tear four large sheets of heavy-duty foil, each big enough to fully enclose a chicken breast and vegetables. Set the grill to medium heat.
02 -
In a bowl, whisk together barbecue sauce, all the pineapple juice from the can, soy sauce, and minced garlic until homogeneous.
03 -
Place one chicken breast onto the center of each foil sheet. Distribute zucchini slices, bell pepper squares, and 2 pineapple rings evenly over each serving.
04 -
Spoon approximately 2 tablespoons of the pineapple barbecue sauce over each portion, ensuring an even coating. Reserve about 60 ml (1/4 cup) sauce for finishing.
05 -
Fold the foil tightly around the chicken and vegetables to seal securely with no leaks. Place the packets on the preheated grill, cover, and cook for 13–15 minutes, turning once at the halfway point.
06 -
Carefully open the foil parcels, avoiding steam. Brush reserved pineapple barbecue sauce on the cooked chicken and top with chopped green onions before serving.
