Place the pumpkin pieces in a steamer and steam for 10 minutes.
Transfer the steamed pumpkin to a bowl and mash it.
Melt butter in a pan, add the mashed pumpkin, and sauté.
Spoon the mashed pumpkin into a small glass cup and make a well in the center.
Crack an egg into the well.

Season with salt and pepper.
