My friend, Kendra, who enjoys cooking, needlecrafting, helping the homeless, and shuffleboard gave me this and said it is really a nice roast to grill when it is too hot to turn on the oven. Notice that you need to marinate it the night before, I have not included the marinading time in the preparation time. Because charcoal grilling varies with temperature of coals, size of grill, weight of meat, etc. I urge you to use your meat thermometer to get it to your own family's preference.
