01 - Press tofu for at least 15 minutes to remove excess moisture, then cut into 3/4-inch cubes.
02 - Toss tofu cubes with cornstarch, salt, and black pepper until evenly coated.
03 - Heat vegetable oil in large nonstick skillet over medium-high heat. Fry tofu cubes, turning occasionally, until golden and crispy on all sides, about 8–10 minutes. Remove and set aside on paper towel-lined plate.
04 - In blender, combine mango, sweet chili sauce, soy sauce, rice vinegar, maple syrup, garlic, chili flakes, and ginger. Blend until smooth.
05 - Pour mango mixture into small saucepan and bring to simmer over medium heat. Stir in cornstarch slurry and cook for 2–3 minutes, stirring constantly, until slightly thickened.
06 - Add crispy tofu to pan and gently toss to coat evenly in glaze.
07 - Transfer to serving platter. Garnish with cilantro, green onions, sesame seeds, and lime wedges if desired.
