How to make Tofu like Whole Foods Vegetarian General Tsao's "chik'n"?

I've had this a couple of times and it's pretty good. I asked the clerk what it was made from and how it was made he told me extra firm tofu, baked down and basted with sweet and sour sauce. That's pretty much all I could get out of him. I'd like to make this and other imitations that can be used for other recipes that I used to like when I ate some meat base recipes. It cost $9.99 a lb at Whole foods so money is another motivator. Most tofu stuff I've had tastes awful like Tofurkey lunch meat don't how people eat it. This and the Vegetarian Pepper "Steak" are one of the few things I've tasted that actually tastes good and give me hope I might make something good with it. I am not a vegetarian but cutting out as much as meat as possible. I still eat fish a few times a week. I have blood sugar issues and have trouble digesting nuts and find so far cutting it all out makes me ill. I'd appreciate some tips and recipes to duplicate the texture and taste so I have other options.
