Just about any kind of meat can simply be put into the crock pot with some seasonings before you go off to work in the morning and it will be done when you get home. Mine has an "Auto" setting where it cooks on high for 3 or 4 hours then switches to low, which is usually just about perfect. Makes sense to use cheaper, tougher cuts since the long cooking will tenderize the meat. Barbecue sauce, tomato sauce are good, or you can use a can or two of soup such as cream of mushroom. Here's one of my favorites - take a lean pork roast and put it in the crock pot. Sprinkle with spices such as salt, pepper, garlic, chili powder, cayenne pepper - you can get creative. Add a cup of vinegar and cook all day. When you get home, shred it up and serve on warm buns with coleslaw. You can then freeze and use this shredded pork in all sorts of dishes.
