Wash the kabocha squash thoroughly, cut it in half, and remove the seeds.
Place the kabocha in a steamer and steam for about 15 minutes until tender.
Scoop out the inside of the kabocha with a spoon to create a bowl shape.
In a small bowl, mix the egg, milk, salt, and pepper well for the egg slut.
Pour the egg mixture into the hollowed kabocha and top with cheese.
Microwave for about 3 minutes until cooked.
Garnish with parsley or herbs and serve.
