I make these every once in a while, they are a mildly sweet version of rustic pie. I've really only seen them specifically around the Napoli/Campagna region of Italy.
These bring me back to my childhood and fond memories of when I lived in Naples Italy and going to grandma's on Sunday's and going to the smallest of corner bakery and buying 2 dozen at a time and eat them until I was blue in the face. No one could make them as good as this one baker.
They are filled with ricotta, sopresatta and cheese. The dough is buttery with a hint of sugar. (If I only had a time machine)
