Mix together flour eggs, olive oil, white wine, baking powder and salt (to taste) into a workable dough. Dice cheese and ham finely and mix into the dough. Halve olives, remove pits and stir into the dough.
Preheat the oven to 180°C (approximately 350°F). Brush a loaf pan with oil, add dough and smooth the surface. Bake in the oven for about 50 minutes, remove, let cool slightly, then unmold onto a cooling rack and cool before slicing.
