Italians don't like to eat big pieces of meat, but they do like to braise small pieces with lots of vegetables into delicious ragus. In this episode, Lidia creates a delicious meal of celery stalks stuffed with gorgonzola and apples; mouthwatering lamb ragu prepared with an array of peppers and potatoes and for a sweet finish, a gianduia cake made of hazelnuts and chocolate-a Piedmontese tradition.
