Bulgogi
Marinate thinly sliced beef in a traditional Korean marinade, then pan-fry for a delicate balance of sweet and savoury flavours
Bring a large pan of water to the boil. Add the noodles and cook following pack instructions until soft. Briefly rinse in cold water and drain well. Transfer to a large bowl, toss with the soy sauce until coated, then set aside.
To make the eggs, heat the oil in a non-stick frying pan. Add the egg mixture, swirling to evenly coat the bottom of the pan. Cook for about 2 mins, without touching, until the egg is set but just barely browned on the bottom. Flip and cook for 15-20 secs more until the bottom is just set. Slide onto a chopping board, roll into a log and cut crosswise into thin strips. Set the egg strips aside and wipe out the pan.
To cook the prawns, heat the oil in the pan, add the garlic and cook for 10 secs, until fragrant. Add the prawns, season with salt and cook for 11/2 mins, stirring often, until the prawns are just pink. Add the mirim and cook for 3 mins, stirring often, until cooked through. Transfer the mixture to a bowl.
For the vegetables, add the oil to the pan over medium heat. Add the onion and cook for 1 min, stirring often, until slightly softened. Add any juices from the bowl of prawns and toss to coat. Add the mushrooms and carrot, and cook until slightly softened. Stir in the spinach in handfuls, adding more as it wilts. Add the spring onions and noodles, and toss together.
Add the sugar, sesame oil, sesame seeds, soy sauce and a good pinch of salt. Toss well and cook for 2 mins until the noodles are heated through and glossy. Add the egg strips and prawns, and gently toss together. Transfer to a platter, top with the spring onions and sesame seeds, and serve immediately.
