If you can, try the Bollito Misto and Fritto Misto. These are two very traditional dishes and you may only be able to find them in old restaurants far from the tourist circuit. The Bollito Misto is a mix of beef and pork meat boiled with vegetables and eaten with a variety of sauces. The Fritto Misto is a mixture of fried meats and vegetables. Another very typical meal is Bagna Cauda: it consists of a hot garlic sauce eaten with raw vegetables. Try also the "Paniscia vercellese" a typical dish from Vercelli made with rice, beans and sausages.You can eat also fried frogs and good fishes from lake and rivers.
