  2. Chop the parsley and add to the bowl.
  3. Wipe the mushrooms, remove their stalks and add them to the bowl with the Balsamic vinegar mixture. Use a spoon or your hands to make sure the mushrooms are evenly coated, and leave to stand for 20-30 minutes.  
  4. While the mushrooms are marinating, peel and slice the onion into 4 thick slices, wash and slice the tomatoes and wash and shred the lettuce. 
  5. Place the mushrooms and onion slices on a grill pan, and grill for 5-7 minutes on each side, until they are tender when pierced with a fork.
