Cut the onion into rings and the bell pepper into thin strips. Fry both in a large pan or in a wok until the onions are translucent (not brown). Add tomato paste, cumin and minced lamb. Fry everything while stirring and deglaze with the soy sauce. Continue cooking for about 3 - 4 minutes, then stir in the finished red cabbage and let it warm up. Season to taste with pepper (the soy sauce eliminates the need for salt).
Tastes good with potatoes, with flatbread and a yoghurt sauce or with fried Jerusalem artichoke.
