Peel, halve and slice the onion. Clean, quarter and slice the peppers.
Heat the oil in a pan, fry the onion and paprika, add the tomato paste and pour the broth over it, reduce a little until the paprika is cooked through. Season with sugar, vinegar, pepper and salt (be careful, smoked pork is often salty). Put the meat on a plate, pour the sauce over it and sprinkle with parsley.
