I'm a lazy cook, use my crock pot a lot. A piece of meat and some tinned gravy or other liquid and 8 hours later I have "dinner". Last night worked out well for me because my husband was away and got home over an hour late and didn't eat for another hour. The crock pot roast saved the day. I'd added a few veggies a few hours earlier so everything was perfect for him.

I love roasts though, beef; chicken; Monday night, a leg of lamb; you get a meal in 2-3 hours, good leftovers, and you don't even have to do much.
