Potatoes with wheat berries (papas con mote de trigo)

An ancient dish from the country side in Chile. Most of the old chilean dishes are vegetarian, since the meat was really expensive and only enjoy on special holidays.
I hate it as a child and refuse to eat it. Now I can not stop thinking how good it is.
The "mote" is not exactly wheat berries, but is the closest substitution. You can also use barley.
Enjoy!
