Preheat the oven to 400 degrees F, and line a baking sheet with parchment paper. Combine the flour, salt, cheese, fresh rosemary, and water together in the bowl of a standing mixer, fitted with a paddle attachment. Mix on low until the dough starts to form, but you still have loose flour and cheese that hasn't been incorporated into the dough.
Empty the mixture out onto a lightly floured workspace, and knead until the dough comes together into a smooth ball, 2 - 3 minutes.
Flatten into a disk shape, and roll to the approximate size of a baking sheet. Place on the baking sheet.
Sprinkle a little rosemary olive oil over the surface, along with a few pinches of salt flakes or coarse sea salt, and a couple of twists of fresh pepper.
Bake for 15 minutes. Turn the baking sheet around and bake for another 5 minutes.
Serve with rosemary olive oil on the side.
