Preheat grill OR oven to 400 degrees F.
Cut 5 large sheets of heavy duty foil (about 12-inches wide by 17-inches long.) Coat foil generously with nonstick cooking spray.
In a large bowl, toss together all the ingredients.
Divide mixture evenly into 5 equal portions and add to the center of each sheet of foil.
To seal the foil packet, bring the short sides together in the middle and gently fold down over the ingredients, leaving a little space for steam. Then roll up the ends to seal closed.
Place in the oven (on a sheet pan) or on the grill for 25-30 minutes, until shrimp is pink, rice is cooked through, and veggies are tender.
Carefully open the foil pack, expecting hot steam to be released. Let cool slightly and enjoy.
