Add all-purpose flour, spelt flour, yeast, salt, dried herbs de Provence, and extra-virgin olive oil to a large bowl. Mix well, then add water. Stir until a shaggy dough develops.
Transfer the risen dough onto a floured surface. Gently shape it into an oval with an even thickness and then use a sharp knife to cut several slits along the surface to form a leaf-like pattern.
Place the dough on a parchment-lined baking sheet, brush it with extra-virgin olive oil, and sprinkle a pinch of rosemary and some sea salt on top. Bake for 20-25 minutes.
