Bring the chicken breast fillet to the boil in the broth with the celery, the garlic, the chilli and the coriander. Let simmer for about 30 minutes. Then add the peppers, carrots and sprouts and simmer for another 15 minutes. Sprinkle in the Mie noodles, reduce the temperature and stir in the tomato paste and soy sauce. Remove the chicken breast, cut into small pieces and return to the broth. When the pasta is done, season with salt and pepper. Bon Appetit!
