Put the noodles in a sieve over the sink and pour over a kettle of boiling water. Toss to separate, then leave to drain.

Heat 1 tbsp of the sesame oil in a large frying pan over a medium heat. Add the onion and ginger, and fry for 5 mins until softened slightly. Add the broccoli, kimchi and radish, and continue to fry for 5 mins. Stir in the drained noodles, spring onions and soy sauce.

Meanwhile, put the remaining 1/2 tbsp oil in a small frying pan and fry the eggs for 3 mins, or until cooked to your liking. Serve the noodles in bowls with an egg on top, and sprinkle with the sesame seeds and some chilli flakes, if you like.
