Chop sun-dried tomatoes, olives, pine nuts and fresh rosemary.
Dissolve the yeast or the sourdough starter in lukewarm water. Add both types of flour and knead for about 1 minute.
Add the rest of the ingredients and knead until you've got a smooth dough for 3-5 minutes.
Put the dough in a bowl and cover the bowl either with plastic wrap or with a damp kitchen towel. Let it rest for about 2 hours at room temperature.
Carefully shape the baguettes and twist them. Let them rise for another 30 minutes while you preheat the oven to 230 °C with a pizza stone or a baking tray in it.
Bake the baguettes on the super hot pizza stone or baking tray for about 20 minutes.
Make some cuts on the surface of the baguettes and stuff them with herb & garlic butter.
