I created this soup for a very dear vegetarian friend (although it can be easily made non-vegetarian if you prefer), and it quickly became one of his most requested dishes. It is very filling, and great comfort food. Try to make this soup the day before and let it sit in the refrigerator overnight at least. The flavors blend, the curry mellows, and the resulting soup is just fantastic. If you prefer a non-vegetarian version, just substitute the soy sausage patties with regular sausage patties, or even just 1/4 to 1/2 pound of ground beef.
