This came from Gordon Ramsay's book, Fast Food. I found a video of him preparing it on the internet and had to try it. I've made a few changes, substituting some things for what I've had on hand, but it turns out absolutely delicious either way. It can be served with mashed potato or rice, it's very versatile. I like to have a fair bit of sauce to work with, so I don't reduce it as much as suggested.
