Nice one! I've wanted to try my hand at that but I haven't really thought about it for a while.
I made beef pot roast! It was great, used tomato paste (you can use actual tomatoes but I don't like the texture of cooked tomatoes), bbq sauce, worcs sauce, onion, garlic and honey then put in as many carrots as could fit. Then topped the slow cooker up with water and let it cook for 7 hours before adding bulgur wheat to it then cooking for a further 2 hours. Beef was tender af, sauce was vegetable sweet. I'd probably add some hot sauce next time but then 99% of my cooking is adding hot sauce.
