Add the tofu to a large bowl and toss with the oil. Then add the cornstarch and toss once more to combine. Spread tofu into an even layer and air fry at 400F for 22 minutes until golden and crispy.
Meanwhile make the mango sauce: Cut the mango into chunks and set aside in a bowl. Whisk together the soy sauce, maple syrup, lime juice and zest, water, chili flakes and cornstarch until well combined.
In a large skillet warm the oil over medium heat and sauté the ginger, garlic and the white parts of the green onions for 2 to 3 minutes, until fragrant and softened. Then add in the mango chunks and cook for 2 minutes.
Pour in the sauce and bring to a simmer, stirring frequently, until it’s reached your desired thickness. Fold in the crispy air fried tofu and toss until completely coated in the mango sauce. Turn heat to low and let the tofu heat through for 2 minutes.
Remove from the heat, sprinkle with remaining green parts of the green onions, sesame seeds and a drizzle of sesame oil. Serve over rice with steamed veggies of choice and enjoy!
