Preparation / Directions:
Combine all ingredients except butter in a large bowl; toss gently to mix well. Divide vegetable mixture in half. Place each half in center of a 12 x 12" piece of heavy-duty aluminum foil. Dot vegetables with butter. Bring corners of foil together to form a pyramid; twist to seal. Grill foil packets over medium hot coals for 15 to 20 minutes, or until vegetables are tender. Serve immediately.
