I like to cook pot roast in a pot. My mother used roasting bags when I was a kid but I don't understand what their purpose is. I didn't even know they sold them anymore, haven't we learned that it's dangerous to heat up plastic?
I tried those bags for Crock Pots once, but I didn't think that it was all that great.
Yeah, clean up was a breeze, but I agree with @Koukouvagia the thought of melted plastic surly isn't appetizing, especially since Mister K~girl has learned how to do dishes, including the pots and pans /img/vbsmilies/smilies/wink.gif baked goods serve as a great motivator /img/vbsmilies/smilies/lol.gif
