Preheat your oven to 180˚C. Drizzle your halved squash or pumpkin with oil and add your thyme and sage into the centre. Roast for 35-40 mins.
Meanwhile make your filling by combining cous cous, preserved fruit, caper, courgette and kale and toss together in a large mixing bowl.
In a food processor blitz your chestnuts, breadcrumbs and rosemary. Then add your truffle slices into the nutty crumble.
Spoon your filling into each roasted squash and top with a generous layer of crumble. Drizzle with a little truffle oil and roast for 15 minutes until the topping is crunchy and golden.
