A vegan recipe with gluten-free noodles, how do you make it tasty? Fair is fair, the oyster mushrooms are kind of the king of this dish. They give a nice bite and provide that extra umami feeling on your tongue. And that umami feeling? It is enhanced by the special umami sauce. The big advantage of this sauce is that you have all the flavours in 1 bottle. So in theory, you could even flavour the noodles without tahini. But in this noodles recipe, the tahini makes for an extra thick sauce. Enjoy!
