Make the Meatball MixtureIn a large bowl, combine ground chicken, pork, grated ginger, chopped scallions, shallot, sesame oil, salt, and coconut aminos. Stir in one direction until the mixture becomes sticky and cohesive. Add olive oil and mix again. Form into 6 large meatballs, about 5.3 ounces each.
Sear the MeatballsHeat avocado oil in a non-stick or ceramic pan over medium-low heat. Gently place the meatballs in the pan and sear for about 4 minutes per side, flipping carefully with two spatulas or a spatula and chopsticks. Transfer to a plate once golden brown on all sides.
Build the Broth BaseIn a large Dutch oven or clay pot, heat sesame oil over medium-low heat. Add sliced ginger and scallions and sauté for about 1 minute until fragrant.
Add Meatballs and VegetablesCarefully nestle the seared meatballs into the pot. Add cabbage stems and sliced shiitake mushrooms. Pour in chicken stock and coconut aminos. Cover and simmer on low heat for 15 minutes.
Finish with GreensAdd the cabbage leaves and optional bok choy. Simmer for an additional 5–10 minutes, or until the greens are tender. Adjust salt or coconut aminos to taste. Serve hot with broth and veggies.
