Finely mince the green onion. Mix all the ingredients for the negi shio sauce in a bowl.

Wrap the silken tofu in kitchen paper and microwave at 600W for 1 minute. Pat dry and cut into 6 equal pieces.

Lay the pork slices slightly overlapping on plastic wrap. Sprinkle with salt and pepper, then dust with potato starch.

Place a piece of tofu on the prepared pork slices. Roll from the edge to wrap the tofu completely.

Heat salad oil in a frying pan over medium heat. Place the rolls seam-side down and cook until browned, turning occasionally. Reduce heat to low and cook for 3 more minutes to ensure the pork is fully cooked.
