In a 12-inch skillet, heat the oil and stir in the curry powder until blended.
Add the onion; when it's sizzling, add the broth and cabbage.
Cook over medium heat, stirring, until slightly wilted, about 2 minutes.
Add more liquid if needed.
Cover and cook, stirring occasionally, an additional 6 minutes, until tender-crisp.
Sprinkle with peanuts and serve.
