From flour, salt, yeast, milk, yolks and lard, make a dough that is kneaded well, then let it rise in the heat. From the dough, spread a sheet that is placed in a rectangular tray and greased with ketchup.
Place the diced kaiser and salami over the dough, sprinkle with the cheese, pepper and oregano.
Bake for 20-25 minutes. Serve hot.
