Let's start by gathering all the ingredients. We will make the bread dough first.
Sift flour into a large mixing bowl. Add in all the other ingredients and about 3/4 of the warm water. Stir to combine, or, if using a stand mixer, use the dough hook attachment. Slowly add more water as required until all the dry ingredients are absorbed. You may not need all the water. Once the dough comes together, knead for about 8 to 10 minutes (or about 5 minutes using mixer on low speed) until the dough is smooth and elastic.
Shape dough into a ball, and place in a lightly oiled bowl. Cover and leave to proof in a warm spot for one hour, or until the dough is slightly puffy.
Preheat the oven to 400°F (204°C) and prepare the muffin pan and filling.
When ready, place dough on a well floured work space. Punch down and use a rolling pin to roll out the dough into a rectangle, about 20" x 12" (50cm x 30cm).
Place the ham slices in 2 stripes on the dough, lengthwise (parallel to the long sides). Next, place the red peppers on top and then the manchego cheese.
Then, carefully scatter the chopped olives evenly all over the dough. Finally, liberally sprinkle the fresh ground pepper all over.
Next, on the long edge closest, firmly roll the dough into a giant Swiss roll. Press lightly along the seam to seal and rest the rolled up dough on the seam.
Using a sharp knife, cut the roll into 12 even pieces. Place each one with into prepared tulip-lined muffin pan, making sure that the spiral is visible.
Cover with greased plastic cling wrap and let it rest in a warm place for another 45 minutes, or until puffy.
When ready, pop into the preheated oven and bake for 25 minutes or until the tops are golden. Remove from the oven, lightly drizzle extra virgin olive oil on top of the muffins.
Serve warm, or at room temperature. Buen Provecho!
