I got this from an issue of Vegetarian Times when I was in college longer ago than I care to admit. It was from an article on 15 minute meals. As I recall, all of the recipes were pretty good, but I've since lost that issue and this is the only recipe I can remember. I made it for my mom and she loved it so much, it became the de rigueur Christmas Eve soup. It's stupendously easy and sooooo delicious--hearty and warming on a cold day. I only make it during the cold months because highly-flavored sweet potatoes (or yams, if that is your preference) are essential.
