The "national dish" of Württemberg is Spätzle, a freshly prepared pasta made from eggs, flour, salt and water and nothing else. It is typically served topped with cheese Kässpätzle or lentills and Wiener Sausage Spätzle mit Linsen und Saitenwürschdle, as the sausages are of course not called "Wiener" around here.
Another speciality, mostly eaten as a side-dish, is potato salad Kartoffelsalat which, in contrast to the northern German variety is prepared with broth instead of mayonaise, creating in effect a completely different dish.
