Cut the meat into longish pieces. Peel and chop the onions. Heat the lard in a pot and fry the onions in it until transparent. Deglaze with some water, stir in paprika and tomato paste.
Bring to the boil. Steam meat strips in it, season with salt. Cut the sauerkraut a little bit smaller, add it and stew everything covered over medium heat for about 10 minutes. Stir occasionally, adding a little water as required.
However, the meat should only braise in a little liquid. Wash the tomatoes, possibly skin them and cut them into slices. Add beans to the meat and braise for another 20 minutes. Add the tomatoes and peas 5 minutes before the end of the cooking time.
For the dumplings, mix flour, salt, eggs and 100 ml water and work the dough until it starts to bubble. Bring salted water to the boil in a large, shallow pot. Press the dough in portions through a cam sieve (button sieve) or pluck the dough from a wooden board with a knife.
The cams are cooked when they float on the surface. Then rinse with cold water, drain and toss in hot fat. Serve with the meat.
