Directions

• Cut the tuna steak into thin strips and place in a bowl with the teriyaki sauce lime zest and juice. Add a grinding of black pepper. Stir gently to coat the tuna in the marinade, cover with cling film and chill in the fridge for 10–15 minutes.
• Lightly spray a wok or deep frying pan with oil and set over a medium heat. Add the spring onions, garlic, sweetcorn, mange tout and broccoli and stir-fry briskly for 2–3 minutes.
• Add the tuna and the marinade to the pan and toss gently with the vegetables. Stir-fry for 2–3 minutes depending on how well cooked you like your tuna. The vegetables should be slightly tender but still a little crisp.
• Transfer to a warm serving bowl, sprinkle with the herbs and chilli and serve immediately.
