Cut the pieces of meat into thin slices. Roast the onions and garlic in lard in a large casserole until light brown, quickly stir in the paprika powder, add the meat slices and fry, turning frequently, until the resulting juice is simmered. Fill up with 400 ml water, add the sausage slices, paprika strips and tomato cubes, cover the saucepan and slowly cook the goulash on low heat until the meat is cooked through. Season to taste with salt and pepper.
