Bring mixture to a quick boil, then reduce heat to low. Cover pan and cook rice on low simmer for 20-30 minutes, stirring once halfway through cooking time, until liquid has all been absorbed into the rice.
Check on the rice at the 20 minute mark. If rice needs more cooking time to absorb more liquid, continue cooking. Keep an eye on it, so that you don't burn the rice. When rice is done, place it into serving dish and garnish with cilantro, if desired. Serve and enjoy!
