Japanese beef with soba noodles

Mix together 3 tbsp of the soy sauce, the garlic, cornflour and wasabi in a medium-sized bowl. Add the beef and stir until well coated. Set aside.

Bring a saucepan of water to the boil, add the noodles and cook for 5 minutes or according to the packet instructions.

Meanwhile, heat a wok or heavy-based frying pan until really hot, then add half of the oil and swirl to coat the wok. Toss in the red pepper, spring onions and mushrooms and stir-fry for 4 minutes or until softened. Remove from the wok with a draining spoon. Drain the noodles well and set aside.

Heat the remaining oil in the wok, then add the beef and stir-fry for about 4 minutes or until just tender. Remove with the draining spoon.

Pour the stock and remaining 2 tbsp soy sauce into the wok and add the noodles and vegetables with the nori and coriander. Toss well, then add the beef and toss again. Pile the noodles, vegetables and beef into bowls and spoon over the broth. Serve immediately.
