Crack 3 medium egg(s) into a mixing bowl and add ½ tbsp sugar, 1 tbsp sake and 1 pinch salt. Whisk them together until well combined.
Take a non-stick pan and heat it on medium. Add a small drizzle of cooking oil and pour in the egg. Allow it to firm up a little before mixing to make it scrambled.
Transfer the scrambled egg to a bowl and set aside for later. Wipe out the pan to remove any egg residue.
Return the pan to the heat and add 150 g ground chicken. (Add a little more oil if necessary.) Cook until lightly browned.
Add 1 tbsp soy sauce, 1 tbsp oyster sauce, 1 tbsp sake, 1 tbsp mirin and 1 tbsp sugar to the mince and cook on a high heat until the liquid is completely reduced.
Once all the liquid is gone, remove the pan from the heat.
Bring a small pot of water to a rolling boil and add 1 pinch salt. Add 60 g spinach and blanch for 1 minute. Once done,
Drain the water and place the blanched spinach in a small bowl. Add 1 tsp soy sauce, 1 pinch sugar, 1 tsp sesame oil and ½ tsp white sesame seeds, and mix thoroughly.
Dish up 2 portions cooked Japanese short-grain rice into separate serving bowls.
Arrange the egg, soboro chicken and greens on top.
Garnish with 1 tsp red pickled ginger (benishoga) (optional) on each portion and enjoy!
