Use a good homemade stock here, if possible, because its flavor will be the basis of this simple porridge. I like the nutty, textured quality of whole grains in this dish, but feel free to use white rice or a combination of white and brown rice. And if frying chicken at the last minute is not something you want to tackle on an evening, a handful of just about any leftover meat pulled from the bone, or from a store-bought rotisserie chicken, is a perfectly acceptable substitute.
