This recipe came from: http://www.care2.com/channels/solutions/food/1056 It is absolutely divine. It even has non-tofu people singing its praises. It is a great "starter vegetarian" type recipe. I like to serve it with some plain rice.
This is an easy and versatile meal (not to mention low fat and full of good stuff!) This is a regular at our house, and we use whatever vegetables we happen to have laying around. I have also substituted low-fat cottage cheese for the sour cream and found that to be a nice change. I make this with no salt and season at the table, as everyone at my house has different sodium preferences. Adjust to suit your tastes.
This is a really yummy vegetarian dinner option. Even my non-vegetarian husband said it was great. Don't neglect to freeze/thaw/press the tofu as this will give the tofu a better, chewier texture. For additional flavor you can marinate the tofu in a bit of soy sauce and sesame oil.
