Gochujang Beef Udon Noodles

Thinly slice the beef. Mix with soy sauce, sesame oil, garlic and black pepper, then leave to marinate while preparing the remaining ingredients.

Slice the red pepper, trim and separate the pak choi and finely slice the spring onions. Mix gochujang, soy sauce, rice vinegar and honey for the sauce.

Heat cooking oil in a large wok or frying pan over high heat. Stir-fry the beef until browned and just cooked, then remove and set aside.

Add the remaining oil, then stir-fry the pak choi, red pepper, garlic and ginger until tender-crisp.

Add the udon noodles and prepared gochujang sauce. Toss thoroughly and stir-fry until the noodles are piping hot and evenly coated.

Return the beef to the pan and toss together. Adjust salt and black pepper separately if needed, then finish with spring onions and sesame seeds.
