Tasty Slow Cooker Recipes?

I am looking for a really tasty slow cooker recipe. I have some friends coming over and I couldn't be bothered to cook at the last minute so thought i'd stick the cooker on. So far i've tried curry and those meal bases from the supermarket which weren't that great and i've tried a beef in flower with veg which was okay and a sweet and sour pork with cranberry which was awesome. What are your tastiest slow cooker recipes?? TIA!!
