Cook the aromatics. In a large skillet, heat the oil over medium-high heat. Add the onion and sauté for 4 to 5 minutes, until softened. Add the garlic and ginger and stir together for another minute, until fragrant.
Make the curry. Add the chickpeas, coconut milk, broth, curry powder, garam masala, cumin, and salt. Stir everything together, bring to a boil, then reduce the heat to medium-low and simmer for 10 minutes, so that the flavors can meld.
Add the finishing touches. Turn off the heat and stir in the cilantro and lime juice. Serve the curry over rice, and garnish with more cilantro and lime wedges.
