I recently visited the north of Italy where i returned to the same restaurant in Stresa on Lake Maggiore three times . Their seasonal special, home made sausages with chestnuts and polenta, was so tasty I had it twice. I haven’t been able to find a recipe for that dish, but this dish from ” Rick Stein’s Food Heroes” is a good second best. If you cannot get hold of Luganega sausages in your local Italian deli then any Italian sausages flavoured with garlic and fennel will do.
