Wash the perilla leaves thoroughly and remove excess water.
Crack the eggs into a bowl, add a pinch of salt, and whisk well.
Add cooking oil to a pan and heat it over medium-low.
Pour a thin layer of the egg mixture into the pan and evenly spread perilla leaves on top.
When the eggs are halfway cooked, gently roll them up as they cook.
Let the rolled omelette cool, then cut into bite-sized pieces.
