Cut the turkey schnitzel into strips, season with plenty of salt and pepper. Heat the sunflower oil in a large non-stick pan and fry the turkey strips in it. Meanwhile, cut the onion into large cubes and the tomatoes into quarters or eighths (depending on size). Add the tomato paste to the turkey strips and fry for about 3 minutes, stirring occasionally. Add onions and garlic and fry until the onions are lightly roasted. Add the mustard, olive oil, tomatoes, cream and processed cheese and simmer for about 5 - 10 minutes over medium heat, stirring occasionally, until the cheese has melted. Season to taste with paprika powder, oregano and pepper. Noodles go well with it.
