Heat the oven to 220C/fan 200C/gas 7. Peel the pumpkin wedges and cut into bite-sized chunks. Tip onto a large, shallow oven tray and drizzle with 2 tbsp olive oil. Add the mace, chopped sage leaves, bashed garlic cloves and some seasoning. Toss everything together with your hands until evenly coated, then roast for 25-35 minutes or until the pumpkin is tender and lightly golden at the edges.
