Brush the cooking grates clean. Grill the mushrooms, gill sides down, over direct medium heat, with the lid closed, until they begin to soften, 4 to 6 minutes. Brush the cap sides with some of the remaining marinade from the plate, turn them over, add ¼ cup of cheese on top of each mushroom, close the lid, and cook until tender when pierced with a knife, 4 to 6 minutes. During the last minute of cooking, place the bread crumb mixture evenly on top of each mushroom. Remove from the grill, season with pepper and salt, and serve immediately.
