Once it started to boil, add fish sauce and chicken bouillon cubes.
Lower to fire to low heat to let it simmer for 20 minutes. Make sure you cover the pot with the lid to let it cook faster.
Add green papaya in the pot, and let simmer for 3 minutes
Add the spinach, and let it simmer for additional 2 minutes before turning off the fire. Do not remove the lid of the pan since the steam will help continue cooking the vegetables.
