Cut the pumpkin into quarters and scrape out the seeds.
Chop the pumpkin into chunks (leaving the skin on for now) then place the quartered pumpkin onto a roasting tray and drizzle with olive oil.
Roast at 180 degrees centigrade for c 30 minutes then remove from the oven and leave to cool. (Note: you can toast the seeds at the same time – see below).
Whilst the pumpkin is cooking, slice the onion and then peel and crush two cloves of garlic.
Scrape the roasted pumpkin flesh from its skin and add to a large pan, together with the stock, onion, garlic and a small handful of fresh sage leaves.
Bring the ingredients to the boil, then reduce the heat and simmer for 20-30 minutes until the pumpkin flesh is soft.
Place the contents of the pan into a blender and blend until smooth. Return the soup to a pan, season with salt and pepper to taste, and heat through. Serve and dress with a fresh sage leaf and toasted pumpkin seeds.
Rinse the seeds and remove any remaining strands of pumpkin flesh.
Boil a small pan of water (c 2 cups of water) and add the seeds and a pinch of salt. Bring the water to the boil, then reduce the heat and simmer for 10 minutes. Remove from the heat and drain the seeds in a colander.
Tip the seeds onto a baking tray, spray with olive oil and add some rock salt. Toss them around to help coat the seeds. Bake at c 180 degrees for between 5 and 20 minutes; checking until they are brown but not burnt.
When cooked, remove from the heat and leave to cool.
The seeds can be sprinkled on the soup, or eaten as a separate snack.
