Peel and dice the pumpkin into bite-sized pieces. Place in a microwave-safe container, cover loosely with plastic wrap, and microwave at 600W for 6–7 minutes. Mash while warm and mix in butter.

Mince the onion finely.

Heat 1/2 tbsp of vegetable oil in a frying pan over medium-low heat. Sauté the onion until translucent, then add ground pork and cook until browned and fully cooked. Season with salt and pepper. Let cool.

Combine the mashed pumpkin with the cooked pork mixture. Divide into 4 portions and shape into oval patties. Let cool.

Coat each patty in flour, then beaten egg, and finally breadcrumbs.
