I read about this gal a while ago, Stephanie O'Dea. She challenged herself in 2008 to use her crock pot every day for a year. Some of the recipes where outstanding, others not so much. She is very honest about the results.
I picked up two of her cookbooks at Borders and all I can say is YUM. I made her 40 Garlic Clove Chicken and the smell, while it was cooking, was so good I could hardly stand it.
I tried making her Orange and Apricot Pork Chops, the recipe said cook for 8 hours, well my ended up way way over cooked so I am trying it again this afternoon. I am going to check it at 4 hours and see how things are coming along. I think my Crock Pots just are way hotter than hers.
If you are interested in her recipes, they are posted on her blog at this site.
