Madeira-Glazed Portabella Steak Sandwiches

• 8 portabella mushrooms
• 14 cup madeira wine
• 3 tablespoons olive oil
• 2 garlic cloves, bruised
• 12 teaspoon dried oregano
• 2 teaspoons salt
• 1 teaspoon black pepper
• 8 slices onions
• 16 slices rye meal or 16 slices pumpernickel bread
• 8 slices muenster cheese or 8 slices havarti cheese
• 4 cups mixed baby greens

1. Preheat the broiler and place the oven rack in the upper third of the oven.
2. Remove the stems from the mushrooms and, using a sharp paring knife, cut away the gills.
3. Combine the Madeira, 2 tablespoons of the olive oil, the garlic cloves, oregano, 1 teaspoon of salt, and 1/2 teaspoon of pepper in a large bowl; add the mushrooms and toss to coat.
4. Set aside for 10 minutes to marinate.
5. Heat the remaining tablespoon of olive oil in a saute pan set over medium-high heat.
6. Add the onions and saute until soft and translucent, about 5 to 6 minutes.
7. Season with the remaining 1 teaspoon of salt and 1/2 teaspoon pepper.
8. Place the mushrooms and onion slices on a baking sheet, brush with the marinade, and broil until browned and tender; about 4 minutes on each side.
9. When cool enough to handle, thinly slice each mushroom.
10. Fill the sandwich with slices of onion and mushroom and top with a slice of cheese.
11. Place the bottom half of each sandwich with the mushroom, onion, and cheese on a baking pan and place under the broiler until the cheese is melted, about 2 minutes.
12. Top each sandwich with the greens and a second slice of bread.
