Start by pressing your tofu. Either with a tofu press or with plates and some heavy books. Try to press the most water out that you can for about 15- 20 minutes.
Preheat your oven to 450 degrees. Get a baking sheet and spray it with cooking spray; set aside.
When the tofu is done being pressed, take it and either cut it into bite-sized pieces or break it up with your hands. Sprinkle the tofu with 2 TB corn starch and carefully mix to coat the tofu. Place the tofu on the prepared baking sheet and bake in the oven for 20 minutes, flipping halfway through to ensure even browning.
While the tofu is cooking, make your sauce. Mix all your sauce ingredients and stir until combined.
After the tofu has baked for 20 minutes, carefully pour the sauce on the tofu and stir ( the pan will be extremely hot, so be careful)—Bake for an additional 2 minutes.
