Combine broth, ginger and soy sauce to a small sauce pan.
In a small bowl combine cornstarch and water. Stir unil cornstarch is fully dissolved.
Slowly add the cornstarch mixture to the saucepan. Bring the saucepan to a boil.
While the soup is coming to a boil, in a small bowl beat the eggs until combined.
Once the soup has thickened a bit, reduce to a simmer.
SLOWLY drizzle the eggs into the saucepan while stirring the broth mixture in one direction only. The eggs will spread out and begin to look like ribbons.
Take the soup off the heat and then add the green onions. Season to taste with salt and pepper.
