Peel pumpkin, scrape out the seeds, cut it into small cubes. Put them in the microwave-safe dish, cover with plastic wrap and cook until tender for about 3 to 5 minutes.
Mash pumpkin until smooth. Add walnuts and 🄰 and mix. Season with salt and pepper.
Spoon mash into a bowl and top with chopped flat-leaf parsley, if desired.
