Preheat oven to 475º. Boil potatoes 5 minutes until firm. Cut in half and trim bottom of each half so potatoes can stand. Carve a hole in potatoes with melon baller to hold filling.
In skillet, heat 2 tablespoons Bertolli Classico Olive Oil. Crumble and cook sausage over medium heat until no longer pink. Meanwhile, toss potatoes with remaining Bertolli Classico Olive Oil and herbs in bowl. Season with salt and fresh ground black pepper to taste. Place potatoes in baking dish.
Mix cooked sausage, ricotta and Parmesan. Season, if desired, with salt and fresh ground black pepper. Spoon filling into potatoes. Bake until crispy, approx. 10-15 minutes.
Plate potatoes. Top with chopped parsley and additional grated Parmesan if desired. Drizzle with Bertolli Extra Virgin Olive Oil, season with fresh ground black pepper and serve.
