A savory chili-seasoned rub flavors this slow cooker roast. Feel free to use a chuck arm roast, a bottom round, or rump roast in place of the tri-tip. Give this roast at least an hour in the marinade before cooking.

The list of ingredients seems long, but most are spices you probably have in your pantry, and they add flavor to the dish. Avoid overcooking the tri-tip. It should still be sliceable when it's done. If you substitute with a​ pot roast cut, the dish might take longer.
