I have made pot roast on the wsm w/ a piece of chuck. Spiced meat with usual brisket rub, smoked in a deep foil pan uncovered to about 160, then added family pot roast recipe of tomato sauce, ketchup, mustard, worchestire etc to the pan, along with potatoes and carrots, foiled top and smoked to 195-200.
Everyone loved it, including teenage nephews.
