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.

Fun fact of the day…
Only fancy meat gets fed grass anymore
