Lasagne radicchio e salsiccia

Lasagne radicchio e salsiccia is a traditional lasagna variety that's especially popular in Treviso. This strong-flavored lasagna is usually made with a combination of red radicchio from Treviso, lasagna pasta sheets, salsiccia sausage, garlic, scamorza cheese, olive oil, and béchamel sauce (flour, butter, nutmeg, milk, salt, and black pepper). The radicchio and the sausage are sautéed in olive oil with a clove of garlic, and the lasagna is made by alternating layers of pasta, scamorza cheese, radicchio and sausage mixture, and béchamel sauce. The casserole is baked until golden brown and bubbly, and it's then served immediately.
