Peel the yams. Cut each in half. Using a pairing knife or a wood carving knife, carve a face on each of the yam halves.
Preheat oven to 425F. Line a baking sheet with aluminum foil or parchment paper. Lightly spray with oil to prevent sticking. Prick each yam with a fork in a few places, except the face. Place yams on the baking sheet and bake for 40 minutes or until perfectly tanned and tender.
Remove yams from the oven. Style with prepared pulled pork. Serve immediately.
