Heat the oil in a heavy pan over medium high heat. Add the ginger and saute for 1 minute.

Add the ground beef and saute until brown and no longer pink, about 4 minutes.

Stir in the soy sauce. Add the rice and cook, stirring for 30 seconds. Add the water and bring to a boil. Reduce the heat to medium and cook, stirring occasionally until rice is cooked and beef is tender, about 45 minutes. Season with salt to taste.

Serve, garnish with chopped green onions.
