For the chicken and the broth, I did cook the chicken in my pressure cooker and that produced the broth as well, I also let it cool to room temp in the broth for juicy chicken.For the beans, I also cooked them in the pressure cooker, 500 grams (1 lb) and all went into the soup. Drain the beans but reserve the bean broth. To a large pot, add the carrot, celery, onion, garlic, and Italian seasoning. I used two bunches of Chinese celery which is quite thin compared to western celery.
Add the broth, undrained tomatoes, and the drained beans, stir together, if more liquid is needed, add some bean broth or water and bring to a boil then reduce to a simmer and let cook, stirring occasionally, for 30 minutes. While the soup is simmering, cube the chicken.
Stir in the dry pasta and cubed, cooked chicken, cook an additional 10-15 minutes or until the pasta is tender. Taste and season with salt and pepper as desired.
When the pasta is cooked, the soup consistency is much like a stew. Taste and season with additional salt and pepper as desired.
Ladle into bowls, serve, and enjoy.
