Heat the oven to 220C/200C fan/gas 8. Toss the broccoli with the sesame oil, sesame seeds and some salt, then spread out on a baking tray. Roast for about 15-20 mins until charred and tender.
Meanwhile, bring a pan of water to the boil. Add the eggs and cook for 6 mins 30 seconds. Remove using a slotted spoon and lower into ice water to cool for 3 mins before peeling the shells. Mix all the dressing ingredients in a bowl.
Cook the noodles following pack instructions, then drain and toss with the dressing.
Divide between two serving bowls and top each with a halved egg, the spring onions, radishes and charred broccoli. Finish with extra sesame seeds and crispy chilli oil, if you like.
