Drain the tofu and tear it into bite sized chunks. Place it in a bowl and pour over the soy sauce, toss to coat well. Add the cornflour and mix until it is fully coated, set aside.
To make the dressing, mix the soy sauce, rice wine vinegar, sesame oil, crushed garlic, chilli flakes, brown sugar and sliced spring onions together in a large bowl.
Finely shred the carrot (I use a mandoline) and thinly slice the radishes, set aside. Put the kettle on to boil.
Heat a generous drizzle of oil in a non-stick frying pan and add the tofu. Cook, turning every now and again, until it is golden and crisp on all sides.
Add the sesame seeds and maple syrup and cook for another minute, stirring constantly. Set aside.
Place the noodles in a large bowl and pour over boiling water to cover. Use a fork to gently separate them and leave to soak for 2 minutes until they are warmed through.
Drain the noodles well then add to the dressing and toss to coat. Add the sliced vegetables and mix well.
Serve the noodle salad topped with the maple tofu.
