01 - In a bowl, toss the tofu cubes with cornstarch and sea salt until evenly coated.
02 - Heat 2 tablespoons of neutral oil in a large nonstick skillet or wok over medium-high heat. Add tofu and cook for 8 to 10 minutes, turning occasionally until all sides are golden and crispy. Remove tofu and set aside.
03 - In the same pan, add a splash more oil if needed. Sauté minced garlic, grated ginger, and the white parts of the spring onions for 1 minute until fragrant.
04 - Add sliced bell pepper and julienned carrot. Stir fry for 2 to 3 minutes until just tender.
05 - Add halved baby bok choy and stir fry for an additional 2 minutes until greens are wilted but stems remain crisp.
06 - Whisk together soy sauce, water, maple syrup, toasted sesame oil, rice vinegar, and chili flakes in a small bowl.
07 - Return the crispy tofu to the pan and pour the sauce over all ingredients. Toss to coat and cook for 1 to 2 minutes until warmed through and sauce slightly thickens.
08 - Remove from heat. Garnish with toasted sesame seeds and reserved spring onion greens. Serve immediately, optionally over rice or noodles.
