    sp-ring un-yun

    Also known as scallions or green onions, spring onions are in fact very young onions, harvested…

  • 140g udon noodle
  • 200g bag spinach



    Used in almost every cuisine across the world, spinach is an enormously popular green vegetable…


  1. In a large pan, dissolve the stock cube in 1 litre of water and stir in the teriyaki sauce. While the soup base comes to the boil, heat the oil in a frying pan and cook the mushrooms over a high heat, for 2-3 mins, until they turn golden. Add the spring onions and cook for 1 min more, then set aside.

  2. Once the soup base has come to the boil, add the noodles and cook for 4 mins. Add the spinach and cook for 1 min more until just wilted. Stir in the mushrooms, spring onions and some seasoning, and serve.

I accidently used sunflower oil and although it didnt impact the flavour too much i would use vegetable oil next time. I used green beans and hard boiled eggs as extra ingredients. Great recipe, simple to cook and easy to adapt. Also I used thick udon noodles and I will try thinner ones next time.

Lovely and simple to make. Following other people's comments I added soy sauce and chinese cooking wine to the soup base to give it a little more flavour. I also added tofu and edamame beans for protein. A really healthy light dinner.

although this is meant to be for a light supper for 4, if it is going to be the whole meal I suggest doubling the recipe as I found it was pretty small portions.

Quick tasty and easy. The mushroom spring onion combo is a winner but it needs more life in the broth. More teriyaki or miso paste or maybe soy. I'll be giving them all a try.

Quick recipe, we added unsalted peanuts and Indonesean-style fried unions when serving and changed the spinach for pak choi. Unfortunately we both had a lot of flatulence afterwards.

Quick and delicious! Might add some chicken next time to see how it tastes with protein.

Very nice & so quick! Next time, I'll probably try to add 1/2 tsp grated ginger to the broth, though, to give it some kick.

Easy to make but so bland! I added edamame beans and pak choi. It's really missing something but I couldn't put my finger on it.

Perfect for a very quick, easy vegetarian mid-week meal. The combination of the broth and the teriyaki sauce make it very tasty.

This recipe was very quick and simple to make and tasted healthy. I couldn't get teriyaki sauce so ended up using hoisin sauce. Not interesting enough to try a second attempt.

I added red chillies and it really gave it a nice kick. I felt though that it wasn't very filing so next time I cook I will add either more noodles or a beef meat substitute
