Fungi in general are amazing - it blows me away that in western culture we place such little emphasis on their consumption. There are three kingdoms (for the most part) that we can choose to consume - Plants, Animals, Fungi. And yet we just almost ignore the third one for what reason again?
Many mushrooms are also a great meat alternative and have tons of health benefits not found elsewhere and can be great for the environment. They are, for the most part, less concentrated in protein than animals but still much higher than most plants.
