This is a fantastic flavorful, low fat, high fiber dish. You can use regular polska kielbasa, but it increases the fat content tremendously. I've tried a lot of different turkey kielbasas, and Butterball is by far the best - flavor and consistency are very close to regular kielbasa - all that's missing is the fat. You can also use white rice, but then you lose the fiber of the brown rice. Also feel free to adjust the cayenne to your family's taste. The amount here (1/4 t) leaves it mildly spicy.
