Middle Eastern Chickpea & Rice Stew

Heat oil in a large saucepan over medium heat; add onions and cook, stirring often, until tender and well browned, 10 to 12 minutes. Add cumin and coriander and stir for about 15 seconds. Add orange juice and broth. Stir in chickpeas, sweet potato, rice and salt. Bring to a boil; reduce heat to a gentle simmer and cover. Cook, stirring occasionally, until the rice is tender and the sweet potatoes are breaking down to thicken the liquid, about 45 minutes. Season with pepper. (The stew will be thick and will thicken further upon standing. Add more chicken broth to thin, if desired, or when reheating). Serve topped with cilantro.
