Pour the oil from the tuna can into a pan and stir-fry the kimchi first.
Once the kimchi juice is absorbed into the oil, add the eggs and make scrambled eggs in the same oil.
Then, finely chop the cooked chicken breast and add to the pan, stir-frying together.
When everything is cooked, add half a bowl of rice, stir-fry to make fried rice, then spread it out flat.
Sprinkle half a pack of mozzarella cheese on top and wait until the cheese melts completely.
Let everything cool, then place the stir-fried mixture cheese-side up on the gimbap sheets.
Lay half a can of tuna in a line on top.
Roll the gimbap carefully and enjoy.
