Tortano or Casatiello is Italian (Napoletan) Easter bread stuffed with ham, salami, cheese, pork cracklings and eggs.
When risen, roll out the dough with a rolling pin to form a rectangle about half a centimeter (1/4 inch) thick. Brush the dough with butter. Sprinkle with cheese, ham, salami and eggs. Season with pepper.
*I used Croatian Kulen, but you can use any kind of spicy salami like Spanish Chorizo or Italian Pepperoni
