I love crock pot recipes! Yum!
Another one I like too that is almost as quick as Stagebears -
boneless chicken breasts
3-6 cloves of garlic (depending of size and taste)
fresh rosemary of thyme ... or dried
some white wine
and some chicken broth
Then I cook it on high or low depending how much time I have. Sometimes I add tomatoes or veggies. I like flexibility.
I normally dip the chicken in flour mixed with salt/pepper first and quickly cook it in a pan to get it brown - I like the flavor, and the flour helps make a thicker sauce. But I hadn't thought of sour cream ... might have to try that.
Auburnchick -I've subed the cream or cream soup in things for a cream-ish sauce. I normally use milk that I thicken with a roux or slurry (where I mix a bit of flour with milk before adding to the warm milk), but I wonder if you couldn't do something similar with chicken broth or even Lactaid? Maybe you could use cornstarch to thicken the broth ... sort of like gravy?
another idea too
