Cut the cabbage into chunks, and cut the shaved pork into pieces of the same size.
In a bowl, beat the eggs well, then mix in the potato starch.
Heat the pork in a frying pan with oil. Once the pork begins to change color, add in the cabbage and bean sprouts. Add salt & pepper to taste.
Move the pork and vegetables to a different dish, then in another frying pan, begin frying the eggs.
When the eggs are about half done, fold both sides of the egg over. Wrap the egg over the pork and vegetables, and make sure the folded side is down.
Add okonomiyaki sauce, mayonnaise, and green onions to taste.
