Frico is pan-fried cheese, using something like a montasio. Usually it's served on its own with seasonings, but here it's cooked with a layer of sliced potato and some silverbeet (also known as Swiss chard) to make it a meal.
Note You can buy lard from supermarkets, but making your own will give the best flavour here. To render chopped pork back fat, place it in a saucepan and add enough water to come 2cm up sides of the pan. Cook very slowly over low heat until the fat renders. Cool, then chill in refrigerator and scoop off fat from liquid (discarding liquid). Lard will keep refrigerated for 1 month in a sealed jar. Montasio cheese is a semi-hard cheese available from Italian delicatessens.
