I made a whole chicken in a crock pot. Woo hoo! It's like the simplest thing ever, but it was still pretty intimidating... it's a whole chicken.
All I had to do was rinse off the chicken and sprinkle paprika and minced garlic on top. Then I cooked it 7 hours on low. When I got home form work it was hot and ready. The meat was literally falling off the bone.
Here's a great how-to that I followed at The Happy Housewife.
