Do you have some leftover BBQ sauce sitting in your fridge you need to use up? Why not toss it on your roast next time you out on in the slow cooker. I used only about 1/4 of a bottle and it will coat and cook in to the meat nicely as it cooks all day in the slow cooker.
I also add 3 large carrots (sliced), and 2 medium potatoes (cubed) to my 2.5 pound roast in the slow cooker that I cooked on low for 8 hours.
Below is a picture when it was all assembled in the slow cooker and ready to cook.
