I've been making honey-gingered pork tenderloins for years (Google that name - recipe on the Epicurious website.) Won an Iowa State Fair competition. I skip the oyster sauce, no real difference.
Buy a (non-marinated) package of two pork tenderloins. Mix up your marinade and freeze the tenderloins in marinade in ziplock bag(s) to take frozen on a camping trip - thaw before grilling. Marinates as it thaws in the refrigerator.
Recipe includes grill directions for turning and basting often for a total of thirty minutes. One tenderloin serves three or four people. I often serve to guests with rice, roast asparagus and Major Grey mango chutney on the side to serve with the pork.
