I'm a bit of a Le Creuset/Staub girl. This type of slow cooking is new to me!
I have adapted The Silver Palate Chicken Marbella recipe to the slow cooker with great success. It works out beautifully.
Can you elaborate on the adaptations you've made? Chic Marbella is one of my go to recipes for holidays and family gatherings - I'd love to free up some oven space by making it in the slow cooker.
I don't make this every week but apparently Chairman Mao had his cooks do it http://food52.com/recipes...
Cooks Illustrated has a beef barley soup in the crockpot recipe that is the epitome of winter. I always make it the day we cut down our Christmas tree. The recipe is available in their Best Make Ahead Recipe cookbook.
Williams-Sonoma website has awesome slow cooker recipes and agree that Cooks illustrated recipes are pretty reliable.
