Wash the pumpkin thoroughly, remove the seeds, and cut into bite-sized pieces.
Place the pumpkin pieces in a steamer and steam for 15 minutes.
Mix the cooked pumpkin with a pinch of salt and pepper.
Put the pumpkin in an oven-safe dish and sprinkle mozzarella cheese on top.
Bake in a preheated oven at 180°C (356°F) for 10 minutes until the cheese is melted.
