Portobello Cheeseburgers

Spray the mushrooms with nonstick spray and sprinkle with the salt and black pepper. Heat a ridged grill pan over medium-high heat. Add the mushrooms, rounded side up, and cook until they begin to release their liquid, about 4 minutes. Turn and cook rounded side down until almost tender, about 2 minutes. Top each mushroom with 1 slice of the cheese and cook until the cheese is melted and the mushrooms are tender, 1-2 minutes longer.

Meanwhile, toast the muffins.

Layer 1 mushroom, one quarter of the roasted pepper, and 2 teaspoons of the dressing on the bottom half of each muffin. Cover with the muffins tops and serve at once.
