Drain a tofu block with paper towels or a tofu press for at least 10-15 mins.
Cut the tofu into even, medium sized cubes.
Line an air fryer with foil and spray or drizzle the foil with a thin layer of cooking oil. This will ensure the tofu doesn't get stuck to the foil.
Evenly space the cubed tofu pieces in the air fryer, spray or drizzle them with more cooking oil, and sprinkle with salt and pepper.
Air fry at 390F for 18-20 mins, flipping halfway. If extra crispness if desired, leave cook for an additional 2-4 minutes.
While the tofu is cooking, whisk together the sauce ingredients.
Heat the sauce in a pan on medium low heat until the mixture thickens. Once the tofu is done cooking, add it to the pan and mix until all of the pieces are coated in sauce.
Serve on top of rice with a side of carrot slaw or veggies, and garnish with sesame seeds and green onion.
