Sometimes I'll just put a little BBQ sauce in the bottom of the crock pot. I put chicken drumsticks on top and cover with some more BBQ sauce. I put it on low all day. They are SO yummy and falling off the bone!!
I also do roast beef in the crock pot. I just stick it in there with some salt, pepper and vinegar on top. Then I put about an inch of water and again, on low all day. SOOOOOOOOOOOOOOO tender and delicious! You can also put veggies in with it.
I saw a recipe for Crock Pot Lasagna that looked yummy! You put some sauce then your UNCOOKED noodles, ricotta/mozzarella cheese mixture, sauce again...then start over with the noodles and keep layering. Looks DELICIOUS!
