This curry is a flavorful and healthy dish that is perfect for a weeknight dinner. Start by sautéing onions, garlic, and ginger in a pot. Add curry powder, diced sweet potatoes, and chicken broth to the pot and let it simmer until the sweet potatoes are tender. Add halibut and coconut milk to the pot and continue to cook until the halibut is cooked through. Serve with rice and naan bread for a complete meal.
