Of course they're food! They are no doubt healthy because they are so fresh. I used to pick
fiddleheads with my grandfather in the spring. We would also go looking for wild asparagus and giant puffball mushrooms. The puffballs were my favourite because we would slice them and fry them in butter. If you were lucky enough to catch a spring
smelt run as well, you were in for a gourmet meal!
I also tried them and I can say that they are quite edible. Of course, you can not eat one grass, but you can eat for a change.
Not only are they edible, they are delicious and nutritious. There is no comparison to grass other than the green colour.
