Jambalaya is a versatile dish; different combinations of other ingredients can work in this recipe. After adding the rice, be careful when stirring, the less stirring the better. You don't want to pull our excessive starch from the grain--this is not risotto. While simmering, be sure rice is not sticking to the bottom; you might need to add a little water or turn down the heat. If no andouille is available, substitute other sausages, smoked sausage is the best.
