Artichoke and bottarga quiche

A package of ready made round shaped puff pastry
10 medium sized artichokes
2 boiled potatoes
125 gr. sized package of mozzarella
Grated bottarga (as needed)
Extra-virgin olive oil
Salt

Lay the puff pastry in a dish, lightly greased with olive oil. In a bowl, mix the thinly cut artichokes, a bit of oil and salt and the mozzarella cut into chunks. Pour the mixture into the dish lightly closing the edges of the pastry. Place in oven at a medium temperature for about 10 minutes. Once it has finished cooking, remove the dish from the oven and sprinkle the quiche with bottarga. Serve cold. Variation: add the grated bottarga to the mixture of artichokes and mozzarella.
