Wash the kabocha squash thoroughly, peel it, and cut into bite-sized pieces.
Steam the kabocha pieces until they are tender.
Place the cooked kabocha in a pan and mash it.
Crack the eggs on top of the mashed kabocha to form a 'slut' style.
Season with salt and pepper.
Cover with a lid and cook over medium-low heat until the eggs are soft-boiled.
Finish by sprinkling with parsley or herbs.
