Combine your favorite vegetables and herbs (fennel, celery, carrots, thyme, rosemary). This recipe is very forgiving.
Place ingredients in a bowl and toss well to combine.
Stack two sheets of aluminum foil (about 18 inches long) on top of each other. Make a mound of vegetables in the center (about half). Fold in the edges of aluminum and seal well.
Place packs, seam side up, directly on top of the hot coals. Cook about 30 minutes. Remove from coals and carefully open. Serve warm.
