Step 1

Preheat the oven to 190ºC/375°F/gas

Step 2

Peel and chop the squash into large chunks, finely chop the chilli, then place into a roasting dish. Scatter over the cumin seeds and thyme sprigs, then toss together with 2 tablespoons of oil. Season with sea salt and roast for 45 to 50 minutes, or until cooked and lightly golden, turning halfway. Place the couscous in a bowl and pour over enough boiling water to sit 1cm above the couscous. Cover the bowl and leave for 10 minutes. Toast the pumpkin seeds in a dry frying pan. Uncover and fluff the couscous with a fork, stir in the lemon zest and juice, the roasted squash and 2 tablespoons of oil. Serve scattered with the pumpkin seeds.
