  • ½ cup vegetarian Worcestershire sauce
  • ¼ cup balsamic vinegar
  • 1 tablespoon garlic powder
  • 2 slices cheddar cheese or American cheese
  • 2 medium burger buns

Instructions

  • Remove the stem from the mushrooms and peel the top layer of skin off the top (see above for more details). Remove the gills with a spoon and wash the mushrooms well. Pat dry.
  • Combine the worcestershire sauce, balsamic vinegar, and garlic powder in a shallow dish. Add the mushroom and rub the marinade in. Let marinate, turning the mushrooms once or twice, for 30 minutes.
