Chinese Orange "chicken" with Brown Rice

I used TVP chunks for this delicious meal, which are made of soy flour. I used this sauce from about.com:

• 2 tablespoons Chinese rice wine or dry sherry
• 1 tablespoon cornstarch
• Sauce:
• 1/3 cup orange juice*
• 2 tablespoons dark soy sauce
• 1 teaspoon sesame oil
• 1 teaspoon brown sugar
• 1/4 teaspoon chile paste
• 1 clove garlic, minced
• 1 slice ginger, minced
• Oil for stir-frying, as needed
