It's from "The Greens Cook Book" and it's called "Pumpkin soup with Gruyere cheese".
First you roast a humongous pumpkin. At the same time you make a veggie stock outta all of your leftover choppings and peelings from whatever veggies you've eaten lately (they specifically recommend carrots, celery, turnip, plus the seeds and scrapings from the inside of the pumpkin). Season it up with some bay leaves, parsley, thyme, sage and salt to taste. Bring to boil and simmer for 25 minutes. Strain out the veggies and feed them to your earthworms.
Peel the roasted pumkin and fry up some onions in some butter. Chuck it all together in a BIG pot and simmer for another 25 minutes before pureeing the whole pot's worth. Stir in some light cream, then top with grated Gruyere cheese and fresh thyme leaves scattered over the top. Eat several bowls full. Bread is optional.
