Knead the ingredients for the dough well and cover and let rest for half an hour.
In the meantime, cut the lamb, onions and potatoes into small cubes and use the vegetable oil and spices to make an even filling.
Roll out the dough into two thin flatbreads, as you would with large pizzas, and brush with the filling. Carefully roll up into two thick sausages and cook in a steamer for forty to fifty minutes.
Cut into slices to serve and add sour cream or a simple tomato onion sauce to round it off.
Numerous variations are possible for the filling. Instead of lamb, beef or pork can also be used. Pumpkin, cabbage and aubergines are particularly popular as vegetables.
