Pour broth, oil, and sauces into a large pot and heat over medium-high.
56 fl oz (7 cups) chicken or vegetable broth
4 tsp toasted sesame oil
2 tbsp soy sauce
2 tsp chili-garlic sauce
Peel and mince garlic. Peel and mince or grate ginger. Add half of each to the pot and transfer the rest to a medium bowl.
4 cloves garlic
Shave cilantro leaves off the stems; discard the stems and mince the leaves. Transfer half to the medium bowl and set the other half aside in a small bowl.
Trim and finely chop green onions. Add half to the medium bowl and half to the small bowl.
Add pork, eggs, sauces, and pepper to the medium bowl and mix with your hands until well combined.
1 ½ lb lean ground pork
2 eggs
2 tsp soy sauce
½ tsp Worcestershire sauce
½ tsp black pepper
Using a tablespoon measure, form the pork mixture into rounded meatballs and place on a plate.
Once the broth begins to boil, turn down to a simmer. Carefully add the meatballs (a few at a time, to avoid splashing) to the pot. Simmer until pork is cooked through, 5-6 minutes.
Meanwhile, trim bok choy and slice in half lengthwise. Add to the soup along with the remaining cilantro and green onion.
Return soup to a simmer and cook until bok choy is tender, 4-5 minutes more.
