Sprinkle salt and pepper on the pork slices. In a bowl, mix the oyster sauce and mayonnaise to make the Oyster Mayo Sauce.

Fold each lettuce leaf into a 4cm width, then roll it tightly. Wrap a slice of pork around the lettuce to form a log shape (6 pieces in total).

Place the rolls seam-side down on a baking tray lined with aluminum foil. Bake in a toaster oven for about 8 minutes or until the pork is fully cooked.
