How to Make It
In a small bowl, mix the yeast with 1 cup of warm water and let stand until frothy, about 10 minutes. Meanwhile, warm the milk in a small saucepan. Stir in the oil and wine.
In a large bowl, combine 2 cups of the flour with the dissolved yeast. Add the milk mixture to the dough and gradually stir in the remaining 5 cups flour and the salt. The dough should be very soft, but if it is too wet to knead by hand, add more flour. Turn the dough out onto a lightly floured work surface and knead it until satiny and smooth, about 5 minutes. Place the dough in a lightly oiled bowl, cover with a damp kitchen towel and set aside in a warm place to rise until doubled in bulk, about 1 hour.
Heat the oil in a large nonreactive skillet Add the onions and cook over moderately low heat until softened but not browned about 12 minutes. Stir in the tomatoes and cook until they begin to dissolve about 5 minutes. Remove from the heat and stir in the parsley, olives, capers, anchovies and cheese. Season with salt and pepper.
Soak the bread in warm water until softened, then squeeze out as much water as possible. Tear the bread into small pieces. Ia medium bowl, combine the bread, pork, egg, cheese, parsley, crushed red pepper, black pepper, oregano and salt. Knead the mixture thoroughly with your hands.
Punch down the dough and pull off 60 to 70 walnut-size pieces. Roll the pieces into little balls and set them on a lightly floured sheet. Cover with a dampened cloth and let rise until billowy and nearly doubled in bulk, about 1 hour.
Working with a few pieces of dough at a time, roll out each ball on a lightly floured surface to a thin 4-inch round. Place 1 tablespoon of a filling on each circle, just to one side of the center. Lightly brush the edges with water, fold in half to enclose the filling and seal the edges with a fork. Set each tart on a rack as it is finished; repeat with the remaining dough and filling. Let the tarts dry for at least 15 minutes after the last one is completed.
In a deep skillet, heat 1 1/2 inches of oil to 380°. Working in batches of 4 or 5, carefully slide the tarts into the hot oil and fry until golden on both sides, about 5 minutes. Using a slotted spoon, transfer the tarts to a rack to drain. Serve immediately.
