Chop onion, scallion, and ham into small pieces.

Heat a pan with a small amount of cooking oil and sauté the chopped ingredients.

Add 1/2 cup of cooked rice to the pan and break it apart with a spoon.

Mix ketchup and chili sauce in a 1:1 ratio and add to the rice. Stir well.

Cook until the sauce is fully absorbed into the rice. Set aside the fried rice.

Crack 3 eggs into a bowl, add herb salt, and whisk until smooth.

Heat another pan with a small amount of oil and pour the egg mixture evenly to create a thin layer.

When the egg starts to set, place the fried rice on the egg, about 2/3 from the edge.

Roll the egg over the rice like a sushi roll, adding more egg mixture as needed.
