Slice an onion and brown in a pan with olive oil.
Cut and peel your butternut into small cubes and sauté in the pan over medium heat. Stick a fork into a cube of butternut to check it is cooked. It should go in easily.
Add the sliced mushrooms. Add the corn too. Stir gently. Add a teaspoon of nutmeg and an inch of grated ginger. Season with salt and pepper. Leave to cook for a further 5 minutes.
At the end of cooking, scatter a handful of pumpkin seeds. Serve hot.
