Ok, I am totally in love with buna shimeji mushrooms (Beech Mushrooms) my not-so-local Hong Kong Market carries these (of course) and every Saturday there is a sweet little lady who is cooking them in the wok with oyster sauce and soy. The little sample I get is heavenly. So I generally buy several packages. I use them in stir fry and they are divine with a roast. I find myself replacing my baby bellas with buna shimeji.
So how are you using them? And if you aren't you need to try some soon!
