Drain the olives of any brine and then toss them with 2 tablespoons of flour to lightly coat them. Set aside.
Mix the flour with the baking powder. Add the eggs and, using a wooden spoon, mix into a stiff dough. Stir in the oil and the wine and keep stirring until smooth, or as smooth as you can get it with a couple of minutes of mixing. (You could use a hand held mixer or a stand mixer to do the mixing for you). Stir in the floured olives, the ham, the cheese, and the pepper. You shouldn’t need to add salt, because the ham, cheese and olives all contribute enough salty taste.
