- 1 tablespoon butter
- 1/2 pound mushrooms, cut into thin slices
- 1/4 teaspoon salt
- 1/8 teaspoon fresh-ground black pepper
- 4 teaspoons chopped fresh sage
- 8 slices from a large round loaf of country-style bread, or other bread
- 2 tablespoons butter, melted
- In a large nonstick frying pan, heat 1 tablespoon of the butter over moderate heat. Add the mushrooms, salt, pepper, and dried sage, if using, and cook, stirring frequently, until golden brown, about 5 minutes. Stir in the fresh sage, if using. Put the mushrooms in a bowl and wipe out the pan.
- Using a pastry brush, coat one side of 4 slices of the bread with half of the melted butter. Put them, buttered-side down, on a work surface. Top the bread with the cheese and then the mushrooms. Cover with the remaining 4 slices of bread; brush the tops with the remaining melted butter.
- Heat the frying pan over moderately low heat. Add the sandwiches and cook, turning once, until golden, about 2 minutes per side.
