Very poorly which is why ruminant animals like sheep and cows have three or four stomachs - they need the extra digestive cavities filled with very interesting bacteria cultures to process all that tough cellulosic material.
However, people do eat grass, at least a seed, in the form of various cereal grains like wheat and barley and rice. Those are all grasses!
How well do you digest grass?
The figure may be wrong, but a quick search told me about 4% of cows in the US are gras-fed. They mostly eat grains, which you could eat too.
Sounds like an fairly unhealthy diet to have so much grain.
