Vegan Japanese Winter Squash and Leek Soup
Be forewarned, leeks are great at holding grit, as you'll discover when you slice it the long way!
Vegan margarine can be used in place of the oil if desired.
You can also puncture the squash a few times and put in the microwave on the 'baked potato' setting. Then slice it open in two, scrape out the seeds and fibers, and do it again until the flesh is soft.
