Preheat oven to 400 degrees F. Coat an 8-inch loaf pan with cooking spray.
Place dough on a flat surface and knead in olives and rosemary. Roll dough out to a 12-by-8-inch rectangle. Starting from the shorter end, roll up, jellyroll style. Place dough in prepared pan. Brush the top of loaf with olive oil. Bake 15 minutes, until puffed up and golden brown.
