You can also grill the mushroom slices, following the instructions for Perfect Grilled Vegetables.
Preheat the oven to 400°F. Line a baking sheet with foil.
Rinse the mushroom tops with cool water or wipe with a wet paper towel to remove any excess dirt. Dry thoroughly. Place the mushrooms upside-down on the prepared baking sheet. Remove the stems by gently breaking them off, and drizzle the cooking fat evenly over the mushrooms. Season with the salt, pepper, and garlic.
Roast for 10 minutes, then flip and roast for another 10 minutes, until fork-tender. Allow to cool, then stack a burger and fillings between two mushroom caps and serve.
