Step 1

Start by coating the beef evenly in cornflour. Mixing well in a large bowl.

Step 2

Add half of the rapeseed oil into the pan and increase the heat to high. Evenly distribute half of the beef across the pan and fry for 2 minutes on each side.

Step 3

Repeat with the second batch, setting the beef aside. Season with salt.

Step 4

Next, add the remaining rapeseed oil into the pan, along with the mange tout and onion. Season with salt and chilli flakes and fry for a couple of minutes.

Step 5

To that, layer the udon noodles into the pan, then the pak choi. Add a splash of water into the pan and cover with a lid, reducing the heat to medium. Leave to cook for 4 minutes, or until the noodles are loose enough to separate without breaking.

Step 6

Remove the lid and add the beef, soy sauce, sweet soy sauce, rice vinegar and an extra pinch of salt. Stir to incorporate all of the flavours. Serve with a sprinkle of optional coriander and a serving of broccoli.
