I also used light sour cream and it was still great! I squeezed on a little fresh lemon juice, too. :) I didn't have halibut or cod, so I used relatively thin tilapia filets and cooked for just 6 or 7 minutes. I'm totally making this one again.
Edit: I notcied in the reviews of this recipe, a lot of people subbed vermouth or white wine for the second 1/3 cup of water. I think that would be really good. Also, if I were going to add more veggies, it would be little steamed red potatoes or carrots sliced thin, I think.
