peruvian food

One thing I don't really understand about Peruvian culture is how they eat what they eat.  They have the most GORGEOUS selection of fresh produce - anything you can think of and better tasting than you can fathom.

Why then, do they continually eat rice, potatoes and bread?  Don't get me wrong, I love rice.  I love potatoes.  And yes, I love bread.  But not for every meal! 

Here is an example of a typical dish that we eat for lunch while teaching at "Virgen de la Natividad" in Pacca.  Note that there is both rice, potatoes and hot dog.
