Heat 1 tablespoon of cooking oil in saucepan over medium heat. Cook the rice according to the directions on the package. Cut the sausage into 2-inch cubes, add it to the saucepan and cook until well browned. Add the beans and their juices and bring to a boil. Reduce the heat and simmer 5 minutes. The beans should not need salt, as the sausage is salty. Season to taste with pepper. To serve, spoon the hot rice into a serving bowl and pour the sausage and bean mixture over the rice.
