                In a large mixing bowl, blend the flour, active dry yeast, sugar, and salt. Form a well in the center, then pour in lukewarm water and olive oil. Mix with a wooden spoon or spatula until a shaggy dough forms.

                Transfer the dough to a lightly floured surface. Knead for 8–10 minutes until the dough becomes smooth and elastic, adding additional flour as necessary to prevent sticking.
              
              
              
                03 - 
                Place the kneaded dough into a lightly greased bowl. Cover with a clean kitchen towel and let it rise in a warm, draft-free area for approximately 1 hour or until doubled in volume.
              
              
              
                04 - 
                Gently punch down the proofed dough. Knead in the chopped olives, crumbled bacon, shredded cheddar cheese, and rosemary if using, distributing ingredients evenly throughout the dough.
              
              
              
                05 - 
                Shape the dough into a loaf and transfer to a greased loaf pan, or create a rustic free-form loaf on a lined baking tray. Cover loosely and allow to rise for an additional 30 minutes.
              
              
              
                06 - 
                Preheat the oven to 190°C.
              
              
              
                07 - 
                Brush the surface of the risen dough evenly with the beaten egg to promote a glossy crust after baking.
              
              
              
                08 - 
                Bake for 25–30 minutes, or until the crust is golden brown and the loaf sounds hollow when tapped at the base.
              
              
              
                09 - 
                Transfer the baked loaf to a wire rack and allow to cool fully before slicing and serving.
