Housil, well the potato Knödel is not common at all here (unfortunatly, I love them!).Maybe in Alsace they have some...
In France the quenelle contains no potato but they are very good too. In Brittany the Kig-ha-Farz (= Meat and Dumpling) is a meal composed of vegetable, meat and a big buckwheat dumpling cooked together in a broth.
