Cut the meat into cubes. Peel onions and cut into slices. Heat the oil in a casserole and fry the meat thoroughly. Finally add onions, fry briefly and stir in tomato paste.
Season with salt, pepper and paprika and deglaze with broth. Bring to the boil, cover and stew for about 1 hour. In the meantime clean, wash and roughly cut the peppers into pieces. Also clean, wash and drain the tomatoes and leek.
Cut leek into rings, tomatoes into cubes. Add vegetables to the meat after about 30 minutes and braise. Put pasta in plenty of boiling salted water and cook for about 11 minutes. Rinse under cold water and drain.
Stir the sauce thickener into the finished goulash, bring to the boil again briefly and season to taste with salt and pepper. Serve with the noodles in deep plates.
