Pour about one-third of the milk into a saucepan. Cut the butter into a few chunks (so they'll melt more easily) and add to the milk. Heat over medium-low heat, stirring, until the butter melts but without allowing the milk to reach a boil.

Meanwhile, put the flour in a medium mixing bowl, add the remaining milk, and whisk into a slurry. Once the butter has been completely incorporated into the hot milk, ladle some of the warm mixture into the cold flour mixture to warm it. Pour the contents of the bowl back into the saucepan and whisk it in. Stir in the salt.

Over medium-low heat, whisk the mixture frequently- to prevent sticking-as it cooks and thickens. The bechamel is done at about 180u00b0F, when it has reached the consistency of a runny sauce or heavy cream. Grate in the nutmeg and allow the sauce to cool to room temperature. It will continue to thicken slightly as it cools. Use the bechamel immediately or cool,cover, and refrigerate for up to 5 days; bring it back to room temperature before using.

With the dough on the peel, spoon the bechamel over the surface and spread it evenly, leaving about an inch of the rim untouched. Sprinkle the surface with the Parmigiano. Distribute the mozzarella, the cauliflower pieces, and then the olives, garlic, and chili flakes evenly over the pizza. Sprinkle the bread crumbs over the top.

With quick, jerking motions, slide the pie onto the stone. Broil for 3 to 31/2 minutes under gas (somewhat longer with an electric oven), until the top is bubbling and the crust is nicely charred but not burnt.
