Parmigiano-Baked Portobellos with Roasted Red Peppers on Country Bread

Even those who cannot go a day without meat will be happy with this satisfying sandwich. And while at first glance this may seem like a summer sandwich, it is wonderful year-round, especially in the fall or winter, when it makes the perfect complement to a bowl of hearty soup. The parts can be made beforehand: the peppers, well in advance, and the mushrooms, several hours ahead.
