How to make a foil packet:
1. Lay a large sheet of heavy-duty foil or a double layer of regular foil on a flat surface. (Use nonstick foil where noted.)
2. Put the ingredients in the center of the foil. Bring the short ends of the foil together and fold twice to seal; fold in the sides to seal, leaving room for steam. Grill as directed. (Each recipe serves 2 to 4.)
