01 - Set up three shallow bowls: place cornstarch in the first, plant-based milk in the second, and combine shredded coconut, panko breadcrumbs, salt, and pepper in the third.
02 - Dredge each tofu cube in cornstarch, shaking off excess. Dip into plant-based milk, then press firmly into coconut-panko mixture to coat evenly on all sides.
03 - Heat coconut oil in a large non-stick skillet over medium heat. Fry tofu cubes in batches, turning occasionally, until golden and crispy on all sides, about 2–3 minutes per side. Transfer to a paper towel-lined plate.
04 - Whisk together soy sauce, maple syrup, rice vinegar, sesame oil, garlic, and ginger in a small bowl. Keep the cornstarch slurry separate for later.
05 - Wipe skillet clean and add a splash of oil if needed. Stir fry bell peppers, carrot, sugar snap peas, broccoli, and spring onions over medium-high heat for 4–5 minutes until just tender-crisp.
06 - Pour the sauce mixture over vegetables and cook for 1 minute. Stir in the cornstarch slurry and continue cooking until sauce thickens, about 1–2 minutes.
07 - Add crispy tofu back to the pan and toss gently to coat in sauce. Heat through for 1 minute. Serve immediately, garnished with extra spring onions and toasted sesame seeds if desired.
