Rub the sirloin steak with salt and pepper 

Heat up a pan, add some oil

Sear the steak for 3 minutes on each side (adjust cooking time depending on thickness of the steak add some soy sauce for extra browning colour)

Remove the steak from the pan, leave it to rest for a bit then cut into smaller slices (do not get rid of the pan)

In a separate pot, boil the water then add the noodles and dried vegetable sachets 

When the noodles are cooked, transfer them to the pan that you used to cook the steak

Add some of the noodle water into the pan

Add the whole Chapagetti and half of the Neoguri flavour sachets then mix

Add the steak, give it a final stir

Add any additional toppings - I added spring onions and a soft boiled egg
