How to make
1. Break the eggs in a bowl, add salt and pepper and stir well.
2. Cut the nori sheet into 3 equal parts.
3. Put the pan on medium heat and melt the butter, so that the omelette doesn't stick.
4. Add 1/3 of the egg mixture to the pan and right before they're fully cooked, add 1 of the nori parts and 1/3 of the cheese.
5. Form the omelette by wrapping and pushing it toward one end of the pan using a spatula.
6. Repeat steps 4-5 another 2 times.
7. Serve with your favorite sauce.
Note: You need a square pan for Tamagoyaki.
