Combine Parmesan, oregano and parsley; mix well and set aside. In a large mixing bowl, beat butter and garlic. Gradually beat in oil until smooth. Spread over one side of bread. Place with buttered side up in greased large shallow baking pans. Top each slice with 1/4 cup mozzarella. Sprinkle with Parmesan mixture. Bake at 400°F for 10 to 12 minutes or until the cheese is melted and top is lightly browned. Serve warm. Makes about 150 servings (2 slices each).
