I always buy a chuck roast, the marbling (read that as a decent layer of fat) is what makes a crock pot cooked roast tender and succulent. Add some carrots, well scrubbed potatoes, 1/4 cup of water, a dash of Worcestershire sauce, a sprinkling of salt and a grind or two of pepper. Leave it to cook on low for 8-10 hours.
That is it.
(As an aside, yes, I am lagging behind like the baby tomato. When reaching a goal, there is often a plateau - I am on that plateau, looking at the horizon and enjoying the view. I am girding my loins before rising up to finish the hike to the finish line. In this case my finish line will be a wonderful dinner with Handsome Chris on New Years Eve. That is something worth working towards.)
