Cook chicken in a large stockpot covered with water and vegetables and seasonings listed under stock.
Do not let boil. Skim any foam off. Simmer until done. Remove chicken to cool and strain stock. (our dog loves these vegetables added to his dog food)
When chicken is cool, remove from bone and cut into bite-size pieces.
Return stock to stockpot, add carrots, celery and onion. Simmer until vegetables are tender. Add chicken base, parsley and vermicelli or wide noodles. Cook until tender but not over cooked about 4 minutes for vermicelli and 8 minutes for wide noodles. Add chicken. Adjust seasonings.
