This is the ideal dish to warm you up on the cold winter days.
Heat oil in a Dutch oven on medium-high heat, then add scallions, garlic, and ginger. Cook while stirring often until everything turns soft, about 3 minutes.
Add broth, soy sauce, and gochujang and bring it to a boil. Turn the heat down to low, and add tofu and kimchi, stirring once, until heated through, about 3 minutes. Sprinkle with Korean chives, if you like.
