Italian Flatbread Sandwich

What makes this Italian flatbread recipe so indulgent and different is the presence of the lard and the black pepper. After the dough is rolled into a fine layer, the lard is spread all over it and it is re-rolled again into a snail shape. The result is to die for, a layered crispy, soft, peppery, and fragrant piada, ready to be filled with cheese and cured meat.
