In the bowl of a stand mixer, add the flour, yeast & salt. Mix well with a whisk to incorporate the dry ingredients. Add the water and oil. Using a rubber spatula or wooden spoon, mix the ingredients until a rough dough comes together. Attach the dough hook and knead the dough on medium speed for about 7 minutes until you have a very smooth dough.

You can also do this by hand in a large mixing bowl, kneading for at least 10 minutes.

Shape the dough into a ball, then leave to proof in an oiled bowl, covered with plastic or a damp towel until doubled in size. Depending on the temperature of your kitchen, it should take around 60 to 90 minutes.

Preheat the oven to 390℉ and line a large deep baking dish with parchment paper. A 10-inch round casserole dish works well. On a clean floured surface, roll out the dough to a rough rectangle of about 12" by 16". If it seems to be sticking, reapply more flour beneath the dough as you roll.

Distribute the grated mozzarella evenly all over the surface, then the finely grated parmesan, followed by the olives, capers and thyme leaves. Carefully roll the dough up in the length, then cut evenly into rounds of about 1 1/4" to 1 1/2" in thickness. Transfer each round to the prepared baking dish - cut side up - immediately after cutting to prevent the oil from leaking out onto the working surface. If you are using a larger baking dish, shallower slices will cover the larger surface.

Cover loosely with a tea towel to rest for 15 minutes, then bake in the heated oven at 390℉ for 35 minutes or until golden brown and baked through.

Remove from the oven and leave to cool for 15 minutes before sprinkling with salt, pepper, more thyme leaves and another drizzle of extra virgin olive oil. The bread can be transferred to a serving plate by pulling on the edges of the baking paper and lifting it out. Best served while still warm.
