This is my most requested recipe, in part because it is so very easy and in part because it is also quite delicious. It is also very forgiving and will last for many hours in a slow cooker set on low or warm. All it needs is a quick stir every now and then. It is also easy to double or triple or more. For a large crowd, figure one 4-quart slow cooker for every 25 to 30 people. I used 7 slow cookers to feed 200 people at a recent benefit.
