When I use my older crockpot that doesn't have a removable crock I use one of the cooking bags for a large roast or chicken (or even the turkey size cut down). I put everything inside, twist the top and put the cover on. When finished remove the whole thing with no clean-up. I have also kept two soups warm at the same time with 2 different bags. Just put the soups in the bags hot and keep on low to serve at the same time!
That's a very good idea; however there are special crock pot liners out now....I have no idea how much they cost as I've never felt the need to use. I think Reynold's makes them. I don't especially like cleaning a crock pot. I have a large one with removeable crock and then a smaller one w/o. I find I don't like to use the smaller one since it is harder to wash but if you rinse the crock pot, fill with hot soapy water and let soak overnight, it is much easier to clean. Those liners would probably be a real nice convenience.
