Prepare the ingredients: 1 scoop of cooked rice, 1 egg, 1/2 tbsp soy sauce, 1/2 tbsp perilla oil, and 1 tbsp sesame seeds.

Separate the egg yolk from the white and whisk the yolk in a bowl until smooth.

Heat a non-preheated frying pan with 1 tbsp of canola oil and cook the egg yolk into a thin sheet over medium heat. Flip and cook both sides until golden.

Mix the rice with 1/2 tbsp soy sauce, 1/2 tbsp perilla oil, and 1 tbsp sesame seeds until evenly seasoned.

Sprinkle 2 tbsp of mozzarella cheese over the seasoned rice.

Place the cooked egg yolk sheet on top of the cheese-covered rice.

Microwave the dish for 3 minutes until the cheese melts and blends with the rice.
