I've forgotten where this came from, but I have had it for about 10 years now. It is great for vegetarians, and even for non-vegetarians! I am posting the original recipe which calls for Turmeric, but I have never added it and it still tastes delicious. Other changes I have tried include using diced tomatoes (instead of whole), baby carrots instead of a regular carrot. Also I have microwaved the sweet potato for about 5 minutes prior to peeling and cubing, just to cut down on cook time. All of these changes have worked out well.
