Clean mushrooms and remove stem adn any webbing covering the gills. Lightly oil the cap, then turn it upside down and sprinkle STEAKMAKER into the gills, then lightly oil that side. Let stand 30 minutes before cooking over a hot (steak-cooking) fire. Start with cap up for 3-5 minutes, until it starts to sweat, then flip cap down and grill until soft, another 5+ minutes. For the best look, turn the cap 90 degrees after a few minutes to get criss-cross grill marks. Serve as a side or a vegetarian main course, or slep it on a bun for a meatless burger.
