In a bowl, combine ground pork, fish sauce, cilantro, garlic, ginger, and green onion. Mix well and form into small meatballs.

In a large pot, bring chicken broth to a boil. Add meatballs and cook until they are cooked through.

Reduce heat and slowly add beaten eggs while stirring to create egg ribbons.

Stir in bok choy, soy sauce, lime juice, and red pepper flakes. Simmer for a few minutes.
