Cows eat grass, doesn't mean you can!
got me thinking. Corn, wheat, rice, etc are all grass that we eat regularly. I am not sure the human race could survive on the planet without eating grass.
But in all fairness, for the most part humans only eat the grains of the grass.
Can I eat the other parts of the grass also?
If yes, what do I need to know and/or do to prepare the grass for eating?
