Trim pork of excess fat and cut into slices approximately 8 x 3 x 1 inch (about the size of your hand).
Combine all remaining ingredients for marinade. Pour over pork slices in a large bowl or large zip to lock plastic bag. Marinate 4 hours to overnight, turning meat occasionally.
Preheat oven to 350℉. Line a broiler pan with aluminum foil (or a rimmed baking pan with rack placed inside).
Place meat on the rack, reserve marinade for basting.
Bake for 30 minutes, turn over and brush with reserved marinade. Bake for 30-45 minutes longer until pork is cooked to at least 145℉, basting occasionally.
Remove pork from oven and tent with aluminum foil for 10 minutes. Cut into thin slices before serving.
