Preheat a grill pan or grill. Heat the olive oil in a large saute pan over medium-high heat. Add the garlic and cook until fragrant. Add the porcini mushrooms and saute until beginning to soften, 5 minutes. Tear the nipitella or other herbs and add to the pan. Add salt and pepper to taste and remove from the heat.
Toast the bread on the grill pan on both sides. Top with the sauteed porcini and garnish with chopped parsley and a drizzle of extra-virgin olive oil. Serve immediately.
