Cooked this on the gas grill tonight using a 2.75 pound arm roast. Rubbed it all down with garlic powder first then used 6 ounces of soy sauce and covered each side of the roast with the onion flakes. Stuck to the measurements for the mustard and honey and marinated it overnight turning the roast over in the morning. Cooked the roast at a temp of around 375°F over low flame turning it every fifteen minutes and pouring marinade over it cooking a total of one hour or when the temp of the meat is 145°F. This is a great recipe and easy to make. My wife and I loved it!
