Cook the rice according to package directions in a medium saucepan and set aside.
Heat the vegetable oil in a large skillet over medium heat. Add the diced onion and cook until it softens and turns translucent.
Stir in the minced garlic and cook for one minute until fragrant.
Add the curry powder, ground cumin, salt, and black pepper. Stir for 30 seconds to toast the spices.
Pour in the drained chickpeas and the full can of coconut milk. Bring the mixture to a gentle simmer.
Cook uncovered for 10 minutes, stirring occasionally, until the sauce thickens slightly around the chickpeas.
Spoon the curry over the cooked rice and serve.
