How to Make It
Heat a medium saucepan over medium. Add the oil to the pan; swirl to coat. Add the cabbage; cook until tender and golden brown, 3 to 4 minutes, stirring frequently. Add the ginger, garlic, and red pepper; cook until fragrant, about 1 minute, stirring constantly.
Add the broth; bring to a boil. Reduce the heat to low. Add the tomato, squash, onion, chicken, and salt. Simmer until heated through, 10 minutes. Top with the cilantro.
