Clean, wash and, depending on the size, possibly halve the Brussels sprouts. Wash the meat, dab dry and cut into short strips. Heat oil. Fry the meat for about 5 minutes, turning it over. Peel and cut the onion into short strips and add to the meat after 3 minutes.
Top up with stock and 1/4 litre of water. Add Brussels sprouts. Bring to the boil and simmer for 15-20 minutes. Remove seeds from pumpkin, peel, divide into slices and cut into slices. After about 10 minutes add to the stew.
Season to taste with salt, pepper and curry.
