Reserve the seeds to make a batch of Sweet and Spicy Pumpkin Seeds.
Heat oven to 350 degrees. Cut pumpkin into quarters, scrape out the seeds, and discard. Rub flesh with vegetable oil, and place on a baking sheet, flesh side up. Bake until soft, about 1 hour. When cool enough to handle, remove peel and put through a food mill fitted with a medium disk.
