In a large bowl, combine the ground chicken with 1 tablespoon coconut aminos, 1 teaspoon Umami Stir-Fry Powder or Diamond Crystal kosher salt, and ¼ teaspoon baking soda. Toss gently to disperse the seasoning but don’t work it too much or the meat will get tough. Marinate for at least 15 minutes or overnight in a sealed container in the refrigerator.
Heat a large pot or dutch oven over medium-high heat and add 1 tablespoon of avocado oil when the pot is hot. When the oil is shimmering, toss in the diced onion and sliced shiitake mushrooms along with a sprinkle of Umami Stir-Fry Powder or salt.
Sauté the onions and mushrooms, stirring frequently, until the mushrooms have released their liquid and the onions have softened slightly, about 3 minutes.
Add the seasoned ground chicken and cook, stirring frequently to break up any lumps, until the ground chicken is no longer pink.
Add the minced ginger and garlic and sauté for about 30 seconds or until fragrant. Then, stir in the bag of coleslaw mix and pour in the broth.
Season the soup with the remaining tablespoon of coconut aminos and 1 tablespoon offish sauce. (If your broth is highly seasoned, you may need to back off on the aminos and fish sauce.) Give everything in the pot a good stir.
Next, increase the heat to high, cover the pot, and bring the broth to a boil. Once the soup is boiling, decrease the heat to maintain a simmer. Simmer the soup, covered, for 3 to 5 minutes, or until the cabbage is as tender as you like it.
Taste the soup and adjust seasoning as needed with more Umami Stir Fry Seasoning, salt, or coconut aminos. This step is critical for a well-seasoned soup!
Once the soup is seasoned to your taste, turn off the heat and stir in the toasted sesame oil and green onions. Ladle up and serve!
