Peel the onions and cut into thin wedges. Heat the oil in a roasting pan and fry the meat and onions in it. Season with salt, pepper, paprika, chilli pepper and tomato paste. Deglaze with red wine and add the broth. Add the bay leaves and cover and let simmer for about 1.5 hours. Clean the peppers and the pumpkin and cut into pieces. Add everything to the meat approx. 15 minutes before the end of the cooking time. Tie off the goulash if necessary. Rice goes best with it.
