Heat the margarine in a deep saucepan and sauté the onions, ginger and garlic a little. Season with pepper and chilli. Add the potatoes and fry a little, then add the carrots and pumpkin and stir well. Deglaze with the vegetable stock. Reduce the heat and let everything simmer gently for 18 minutes.
Add some lime zest with a grater, add the coconut milk to the saucepan and chop everything up well with the hand blender. Season to taste with a good pinch of sea salt and the juice from the lime.
