1- Peel and chunk potatoes, make it boil in salted water.
2- mash it with a fork adding cheese cubes (I use asiago you can use cheddar), add salt if needed and red crushed peperoncino for that kick
3- on a lightly oiled pan pour the stuff and compress it with a fork to make a 3+ cm thick saucer
4- cook it on a mid+ heat until brown crust
This recipe comes from Friuli, some add an egg when mixing potatoes
