In a large pot, combine broth, aromatics, and spices (all recipe ingredients up to and including fish sauce). Bring to a gentle simmer for 25 minutes to infuse. Strain broth and return to the pot.
Add dumplings to the pot and cook based on the package instructions.
To serve, place zucchini spirals into serving bowls and ladle hot broth over. Place dumplings on top of broth and garnish with cilantro.
Notes
3 hours (if making broth from scratch) OR 40 minutes (if using store bought)
