Cut up chicken and vegetables. Make individual foil packets by placing chicken pieces and vegetables in center of square of foil. Sprinkle with Italian seasoning. Add 1 tablespoon of butter.
Wrap tightly and freeze. I usually double-wrap the packets.
To cook, prepare a good bed of coals on the fire and place foil packets directly on coals. Cooking time will depend on how hot the coals are, so check frequently. Usually takes 20-30 minutes. Remove with tongs.
When ready to serve, top with parmesan cheese.
