When slow cooking a roast lay it on a bed of potatoes or whatever other sides you want, fill the water to the top of the veggies (or taters) then soak the roast in your sauce of choice. Gravity and heat will help the sauce work into the veggies giving them a nice flavor. The roast pretty much always comes out perfectly moist and you get amazing veggies out of the deal.
