1 Boil the potatoes in large quantities with the skin. Once cooked, drain, peel and mash.

2 Add a little salt, parmesan, flour and egg.

3 Take a sheet of parchment paper and make a portion of square potatoes with your hands (if you want, you can flour them a little), Put inside a little ham and mozzarella and cover with another square of potato paste.
