Wash chicken legs, dab dry and sprinkle with salt. Grease an ovenproof dish with oil and place the legs inside. Spread with chilli sauce and roast in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 30-40 minutes.
In the meantime wash the beans, drain them well and clean them. Cut the beans diagonally into pieces. Onions peel and cut into fine slices. Heat the oil in a pan, fry the onions lightly and dust with curry.
Briefly toast the curry and deglaze with broth. Add the beans, season with a little salt and braise covered for 10-15 minutes. Roast sesame seeds in a small pan without fat, place on a plate and let cool off.
Mix starch with a little cold water until smooth, stir into the curry sauce and let it boil for about 1 minute. Stir the yoghurt into the beans and heat up (do not boil any more). Season the bean curry with salt and pepper and arrange in a deep dish with the chicken legs.
Sprinkle with sesame seeds. Garnish with fresh coriander or sprinkle with chopped coriander as desired. Basmati rice is delicious with it.
