I'd always heard those magical things existed...slow cooker liners that you put in your crock pot to make clean up a breeze. For some reason I could never find them or I never had the desire to look hard enough. The truth is they aren't hard to find at all, they just get hidden amongst the many different sizes of Ziploc bags.
I bought 4 boxes of 4 at Target for $1.79 each (I think).
Clean up was seriously this easy. I don't think I've ever cleaned the kitchen so fast. If you don't have these, get some! They are the best...almost as good as the crock pot itself.
