I stir-fried potatoes with plenty of ground sesame seeds and mayonnaise. I added lemon juice in the end for a little sharpness. It's seasoned well, so add to bentos.
I made this dish for lunch boxes.Lemon juice prevents the food going bad when it is hot outside.
At Step 2, if the potatoes stick to the pan, add a little more oil.
Enjoy Japanese food around the world.
