| Place rice and water in a saucepan over medium heat. Bring to a boil, then reduce heat to low and simmer for about 45 minutes, or until rice is tender. While the rice is cooking, brown the ground beef in a deep skillet or wok. Season with Cajun seasoning. When meat is almost done, add the onion, and cook until the meat is browned and the onion is translucent. Stir in the beans, olives, vinegar, and chipolata powder, if using. Mix well, cover, and simmer for 20 minutes over medium-low heat. Add the cilantro during the last 5 minutes of cooking. Serve hot over or mixed with rice.
