Place Broth ingredients in a saucepan over high heat. Place lid on, bring to simmer then reduce to medium and simmer for 8 - 10 minutes to allow the flavours to infuse.
Meanwhile, cook noodles according to packet directions.
Cut bok choys in half (for small / medium) or quarter (for large). Wash thoroughly.
Either cook the bok choi in the broth in the soup broth OR noodle cooking water for 1 min (if noodles required boiling).
Pick garlic and ginger out of soup.
Place noodles in bowls. Top with chicken and bok choy. Ladle over soup, garnish with green onions.
