Pre-heat oven to 450F. Cut 4 sheet of foil into long rectangles (about 12''x12''). Set aside.
Combine all the ingredients in a large bowl. Spoon mixture evenly onto the 4 foil sheets. Fold and seal foil.
Place foil packs on a cooking sheet and bake 20-25 minutes. Serve chicken from foil packets. Be careful when opening packets; steam is trapped inside.
