01 - Toss tofu cubes with cornstarch until evenly coated, ensuring each piece is dusted for optimal crisping during cooking.
02 - Heat 1 tbsp vegetable oil in a large non-stick skillet or wok over medium-high heat. Add tofu and cook, turning occasionally, until golden and crisp on all sides, approximately 6-8 minutes. Remove tofu and set aside.
03 - Add remaining 1 tbsp oil to the pan. Add garlic, ginger, and spring onions; sauté for 1 minute until fragrant and aromatic.
04 - Add carrots, broccoli, asparagus, bell pepper, and sugar snap peas. Stir fry for 4-5 minutes until vegetables are just tender but still crisp, maintaining their vibrant color and texture.
05 - In a small bowl, whisk together soy sauce, sesame oil, rice vinegar, maple syrup, water, and cornstarch until smooth and fully incorporated.
06 - Return tofu to the pan. Pour sauce over vegetables and tofu; toss to coat evenly. Stir fry for another 2 minutes until the sauce thickens and everything is heated through.
07 - Transfer to serving plates, garnish with sesame seeds and herbs, and serve hot alongside steamed rice or noodles.
