Wash the chicken breast thoroughly and cut it into large pieces.
Rinse the rice thoroughly and soak it for 30 minutes.
Put the chicken breast and water into a pot and bring to a boil.
When it boils, skim off any foam and cook the chicken for about 20 minutes.
Remove the chicken and shred it along the grain.
Add the soaked rice to the remaining broth and simmer over medium-low heat, stirring occasionally.
When the rice is soft and porridge-like, add the shredded chicken breast and season to taste.
Add green onion, salt, and pepper to your preference and simmer once more.
