We do them much like that, using the olive oil, except we use Grub Rub, which is a sweet and spicy BBQ rub. Grill them good on two sides, then wrap in foil with another sprinkle of rub, return to grill on lower heat for another 10min or so until done. Let rest a few minutes and then open foil over a serving dish and you have your own "sauce" made from the juices and extra rub. Slice it up and coat all slices in the juices. My crew eats the heck out of it and it is super easy.
