For more surface and crust, butterfly the tenderloin. If you do, mix a double batch of rub so you're sure to have enough. If you don't have a mortar and are using ground spices, crush everything in a small mixing bowl with a wooden spoon.
This tender, juicy pork tenderloin is marinated in a blend of citrus and soy, a little parsley and Worcestershire, and a few other seasonings thrown in. Grilled to perfection, it really is one of my favorite ways to eat pork tenderloin.
Timing for pork tenderloin on the grill -- the method": Close the lid and grill for 7 minutes. Turn the pork over, close the lid, and grill for another 6 minutes. Turn off the heat (keep the lid closed) and continue to cook the pork for another 5 minutes.
