2. For the filling, place the pumpkin, sugar and oil in a large roasting tin and toss together. Roast for 35 minutes, turning halfway, until soft and golden.
3. Meanwhile, for the pastry, put the flour, margarine, sugar and a pinch of salt in a large bowl and, using your fingertips, rub everything together until it resembles breadcrumbs. Add a little soya milk to form the mixture into a soft dough. Wrap the pastry in cling film and place in the fridge for 30 minutes.
4. Meanwhile, make the topping. Place all the ingredients in a bowl and, using a knife, mix the margarine into the plain flour and sugar until it resembles coarse breadcrumbs. Set aside until needed.
5. Roll the pastry out on a lightly floured surface, then press into a 23cm round, fluted tart tin. Prick the base with a fork, fill with baking paper and beans and bake blind for 15 minutes. Remove the paper and beans and bake for a further 10 minutes or until pale golden.
6. Raise the oven temperature to 190°C/fan 170°C/ gas 5. Place the syrupy roasted pumpkin in a food processor together with the creamed coconut. Scrape the seeds from the vanilla pod, add to the processor and whizz until smooth. Spoon into the tart case and spread evenly.
7. Sprinkle the topping over the pumpkin and bake for 25 minutes, until crisp and golden. Cool slightly before removing from the tin. Slice and serve hot or warm with coconut milk to drizzle over.
