Heat the Broth: In a medium saucepan, bring chicken broth to a gentle boil.
Add Seasonings: Mix in the soy sauce, sesame oil, garlic and ginger. Let simmer for 2 minutes.
Whisk the Eggs: Whisk the eggs in a small mixing bowl, furiously, until they are smooth and ever so slightly frothy.
Create the Egg Ribbons: Reduce heat to low. Continue to whisk as you slowly pour the egg into the simmering broth, stirring in a circular motion with a fork or chopsticks.
Season and Garnish: Add salt and pepper to taste. Serve hot in bowls garnished with green onions.
