Gegrilde oesterzwammen

Oil grate.Place mushroom caps on grill.Mushrooms cooked over the grill will cook very fast and become dried out, so move them around the fire for better heat control - don't let them burn! You can let them blacken a little bit on the edges for extra flavor.As the edges begin to toast, add a sprinkle of Parmesan cheese to each mushroom, and lit it melt.Serve and eat immediately!
