Instructions

Clean the mushrooms. Use a damp towel to gently wipe the mushrooms clean. Then use the dull side of a small paring knife or a small spoon to gently scrape off the gills from the underside of the mushroom. (This little extra step is important because this portion of the mushroom can become quite bitter when it's grilled.)
Make the marinade. In a small mixing bowl, combine the soy sauce with the lime juice, scallions, garlic and chili paste, and oil. Whisk until smooth.
Marinate. Pour the marinade into a large Ziploc bag and then add the mushrooms.Use your hands to ensure the marinade evenly coats both sides of the mushrooms. Remove all of the air from the bag before sealing it, and then place it in the refrigerator to marinate for about 6 hours.
Grill. When you're ready to cook, preheat your BBQ or stove top grill over high heat. Remove the mushrooms from the bag, gently shaking any excess marinade back into the bag. (Save this for later!) Put the mushrooms on a large plate and season both sides with the salt and pepper.
Place them on the preheated grill. Grill the mushrooms until they are nicely charred and tender, about 3 or 4 minutes per side. (If you don't hear a sizzling sound when they hit the grill, it's not hot enough yet. Wait for the sizzle!)
Slice and serve. You can serve the mushrooms whole, or once they've slightly cooled, cut them into thick slices and place them on a serving plate.
Pour the remaining marinade into a small skillet, bring to a boil, and then drizzle it over the mushrooms, and serve.
