I used to work with two people from Peru. One day, they brought in a dish that they called "Planta", although I think that just referred to the fact that it had a lot of mashed plantain in it. What I remember from it is that there was a base of mashed plantain, and I think it was fried into a patty of some kind. On top of it was ground meat and vegetables. It was quite good, but searching for "planta" yields basically nothing. The closest I've found seems to be "Majado de Verde", but that seems to be a vegetarian dish that's for breakfast. This was definitely a lunch/dinner thing. It also had a nice sauce with it.
