Egg sandwich filling made with hard boiled eggs takes a lot of time. When you're short on time, this can be made in a frying pan in less than 5 minutes. Have a sandwich for breakfast.
I thought this up when I didn't have time in the morning so added some eggs while frying salmon. These are good for bento when the eggs are cooked throughly.
Be careful not to let this burn. Letting these crisp make the dish look and taste better.
Enjoy Japanese food around the world.
