At left, a pork (lomito) sandwich which I watched a woman make by hand.  
The pork was fatty, tendony, and not good quality.  Whereas many 
sandwiches get richness from mayonnaise, this one got it from a thick 
layer of guacamole.  What a neat idea!  The sandwich also contained salted 
tomato slices. <br />
At right, an empanada containing ground meat, onions, dark olives, and a 
hard-boiled egg.  Although I didn't like it at first, it definitely grew 
on me.  It was better than the sandwich.
