1 lb. lg. white mushrooms, such as shiitake or portabello
5 tbsp. olive oil
1 tbsp. balsamic vinegar
Salt and freshly ground black pepper,
to taste
2 tbsp. freshly grated Parmesan cheese
2 tbsp. finely chopped fresh parsley
Light the grill. Remove and discard a slice from the bottom of each mushroom stem. If the caps are sandy, wipe them with a clean cloth. Brush the mushrooms with 3 tablespoons of the olive oil. When the coals turn gray, set the mushrooms, rounded sides down, on the grill and cook them for 8 to 10 minutes, turning them often. The mushrooms are done when they start to release some of their liquid and collapse a little. Remove them from the grill and cut some of the largest mushrooms in half. If the mushrooms are very large, you can slice them. Let the mushrooms cool slightly. In a small bowl, whisk together the balsamic vinegar, salt, and pepper. Drizzle in the remaining 2 tablespoons of oil, whisking constantly until it is all combined. Pour the dressing over the mushrooms, then cover them tightly with plastic wrap. Refrigerate them for 1 hour. Sprinkle the mushrooms with Parmesan, parsley, more salt and pepper if you like, and serve with grilled bread. Serves 4.
