Preheat your oven to 200 degrees Celsius.
Prepare the ingredients as noted. Begin by adding the pumpkin, onion, garlic and chorizo and roast for 20-25 minutes until the pumpkin and chorizo start to crisp around the edges. Next squeeze the garlic out the skin and add in all remaining ingredients, place back in the oven and roast for a further 20-25 minutes. Remove from the oven, add a drizzle of oil and zest of both lemon and orange. Serve while hot by itself or with a chunk of crusty loaf.
