Cut the pumpkin into bite-sized pieces. Place in a microwave-safe container, add 1 tbsp water, cover loosely with plastic wrap, and microwave at 600W for 2 minutes until softened. Thinly slice the onion.

Cut the bacon into 1cm wide strips.

Heat olive oil in a frying pan over medium heat. Add the bacon and onion, and stir-fry until the onion becomes tender.
