Cut from one of the tenderest portions of the cow, the tenderloin, Chateaubriand is a truly luxurious roast that is perfect for any holiday or special occasion.  Like filet mignon, Chateaubriand is virtually void of any internal fat so it must be cooked with care in order to avoid drying it out.  By wrapping the roasts in bacon prior to grilling, you are not only able to introduce a ton of fat and flavor, but also protect it from the dry heat of the grill.
