Mix 200 ml of wine with oregano, salt and sweet paprika. Cut the meat into cubes, chop the garlic and add both to the wine. Marinate the meat for about 1 hour.
Cut the onion and bell pepper into strips and fry in the oil. Add the meat with the marinade. Simmer on a low flame for about 10 minutes. Add the rest of the wine and simmer for another 5 minutes. Add the grained stock and tomatoes, simmer for another 10 minutes and reduce the sauce a little. Thicken with a sauce thickener if necessary. Season to taste with herb salt, hot paprika, caraway seeds and cayenne pepper.
