I really want to try grilling pork tenderloin but I don't have a clue how to do it. Do you marinade it first? What do you marinade it in? How long do you grill it? Do you wrap it in tinfoil or put it directly on the grill? I have cooked pork tenderloin many different ways but I have yet to attempt it on the grill. Please share your ideas and recipes with me. I have a pork tenderloin in the freezer just waiting to be used! Thanks!
