Cut the onion, carrot and garlic into small cubes and sauté in a little oil. Pour the chicken stock and vegetable stock, bring the soup to a boil and simmer for 15 minutes. Then puree three-quarters so that you can still see a few pieces of carrot and onion. Season with soy sauce.
Mix the flour, egg and milk together and bake a pancake from them. Cut this into thin strips and add to the soup. Finally sprinkle the parsley on top.
