Finely chop the onion and green onion.

In a large bowl, add the chopped onion and green onion, then crack 4 eggs into the bowl.

Add 1 can of tuna, ensuring the oil is fully drained before adding.

Season the mixture with minced garlic and salt.

Add sesame seeds for extra flavor and mix the ingredients thoroughly using a whisk.

Heat a pan with cooking oil over medium-low heat, then pour 2/3 of the egg mixture into the pan.

Once the bottom starts to cook, use a spatula to roll the egg mixture into a roll.
