Vegetarian Sweet and Sour Pork

Sweet and Sour Pork can be found on the menu at just about any Chinese restaurant.  I wanted to make use of the pineapple and ketchup sauce in a vegetarian dish for the herbivores in my house.  I substituted tofu for the pork; you can also use seitan if you prefer (or meat if you're like me). 

I used fresh pineapple to provide natural sweetness and a hint of tang to the sauce.  I also added a little lime juice to brighten it up. To thicken the sauce, I dissolved a little cornstarch in water and added it to the mix. To this, just throw in a few carrots and enoki mushrooms and you're ready for a quick and easy dinner.
