In large saucepan, heat half of the oil over medium heat. Brown chicken in batches, adding more oil as necessary to avoid sticking. Transfer to bowl and set aside.
Add remaining oil to pan and sauté onion, carrot, oregano and basil for about 5 minutes or until the onion is softened. Add chicken stock and mustard and bring to a boil. Add in pasta and celery, stirring occasionally. Reduce heat, cover and simmer for about 8 minutes or until noodles are almost tender. Add chicken along with any accumulated juices and cook for another 5 minutes or until noodles are tender.
Whisk flour into milk and gradually whisk into soup. Simmer and stir for about 3 minutes or until slightly thickened. Add salt and pepper, garnish with parsley and serve.
