Pork meat boil until ready. Onion stew with a little sunflower oil and water, add the diced meat and potatoes, add herbs and paprika. Salt. Add about 1 cup broth and allowed to stew for 5 minutes. Everything is transferred into stew and pour the rest of the meat broth. Bake for about 1 hour. When the potatoes are soft, add the tomato puree and a pinch of sugar to neutralize the acid of the tomato paste. Leave in the oven for about 20 minutes. Finally sprinkle with chopped fresh parsley. If it has become a little watery, can stir 1-2 tbsp flour with water and pour in a pot, stirring and leave in the oven for another 10 minutes.
