Pour the flour and a pinch of salt in a bowl and mix, adding oil and water until you obtain a homogeneous dough.
Spread out the dough on a layer of baking paper with a rolling pin, giving a round shape of approximately 1 cm.
Stuff with thin slices of mozzarella cheese, lard and apple. Fold the edges inwards and decorate them using the tines of a fork. Sprinkle with fresh rosemary and extra virgin olive oil. Cook for 20 minutes in a preheated 200 degrees convection oven.
