Ultimate Vegetarian Soup (Chow)

Tonight I tried a slightly modified version of the Domestic Goddess's Ultimate Vegetarian Soup for dinner. The wife and I both liked it a lot; the sweet potato gave it a really nice succulence.

I went a bit heavy on the oregano and also used a bit of thyme and an extra-healthy dose of freshly ground black pepper. I omitted the diced tomatoes. Finally, I used an amazingly huge sweet potato that was perhaps three times the size of the not-insubstantial Idaho potato.

We'll make this again -- although right now we have 8 frozen leftover servings to work through.
