This is a great meal to serve to company, keeping in mind to start early in the day for roasting time. Growing up on a farm, we always had a freezer full of beef, so mom would make this ever so often when we had a bunch to feed. The flavor is so good people just keep eating and eating. It's like an Italian feast when served with bread and a green, leafy salad. I've never tried it in a Crock Pot or with a "thawed" roast - I'm too afraid it would affect the recipe somehow - but let me know if you try it either way.
