CHEESY, STUFFED PORTOBELLO MUSHROOM BURGERS

Steps:

• Preheat the oven to 425 degrees F. Line 2 rimmed baking sheets with parchment and set aside.
• Roast the mushrooms: Arrange the mushrooms, stem side up, onions and garlic cloves in a single layer on 1 prepared baking sheet. Drizzle with half of the olive oil. Drizzle 1/2 cup water around the mushrooms on the baking sheet. Season generously with salt and pepper. Roast in the center of the oven until the mushrooms shrink in size and become darker brown, 15 to 18 minutes. Remove and let cool.

• Assemble and bake: On the same baking sheet, place 2 portobellos, stem-side up, with some distance between them. Pile half of the filling on each and then top with the remaining mushrooms, pressing gently but firmly down, so it forms a fairly compact sandwich. Bake until the cheese melts, 6 to 8 minutes.
