Add 1 ts fish sauce and 2 tbs chopped green onion to the eggs. Beat well.
When the chicken broth starts boiling, lower the heat to a simmer.
Add the egg mixture to the simmering broth and stir it well with a fork well for 10 seconds.
Close the lid and simmer another 4-5 minutes until the egg mixture sizzles and has a texture like soft tofu.
