I hardly ever use a recipe for my slow cooker, just throw whatever in and turn it on!

My usual would be chuck steak, sprinkle a bit of beef stock and pepper over it, with a dash of worcestershire sauce. Then over the top some chopped up potato, onion and carrot, maybe a tin of diced tomatoes on top. Mine is on for about 6 hours on high, although it probably doesn't need quite that long.
