Tear off a piece of heavy duty aluminum about 12 to 18 inches long. Open a 10 to 16 oz. package of frozen vegetables and empty onto foil. Dot with butter, season with salt and pepper and sprinkle with 2 to 3 tablespoons of water.
Bring sides of foil to center and fold over and over, folding ends of package to seal. Place on grill and cook along with meat.
