Combine the cornstarch, nutritional yeast, oregano, salt and pepper in a small bowl. Add the tofu into a large bowl then toss in the oil to coat. Sprinkle over the dry seasoning mix and toss again to combine.
Transfer the tofu to an air fryer basket and air fry for 15 minutes at 380F, until golden and crispy on the edges.
Meanwhile, whisk together all the sauce ingredients in a bowl (minus the slurry ingredients). Then pour into a frying pan and warm through over medium heat until it’s steaming hot (not boiling). Once hot, add the slurry and continue whisking the sauce until it’s glossy and slightly thickened.
Add the air fried tofu to the sauce, turn the heat to low and stir to coat the tofu completely.
Make it a meal and serve with rice or quinoa and steamed broccoli or another veggie! Enjoy!
