Preheat oven to 400 degrees.
In a large skillet, preferably cast iron, sauté the mushrooms over high heat with 3 tablespoons of olive oil. Season generously with salt and pepper. Sauté until rich in color.
Slice the garlic clove in half and rub the sliced bread with the garlic cloves on both sides. Place on a baking sheet, drizzle with olive oil and bake in the oven just until golden and crisp. Remove from oven.
Spread the toasted bread with the chevre. Season with salt and pepper to taste. Top with the sautéed mushrooms. Finish with a drizzle of olive oil and chopped fresh herbs.
