Mix together the yeast, olive oil, water, milk and the pinch of sugar.
Add the wheat and corn flours, as well as the pinch of salt, and mix until it turns into a dough. Let the dough rest for 30 minutes.
Set aside 1/3 of the dough. Using a rolling pin, roll out the remaining dough and place it in a pan with a removable base, covering the bottom and sides.
Completely cover the dough at the bottom of the pan with the cheese, and cover the cheese with the Calabrese sausage. Cover with a disk made from the dough that had been set aside, trimming the excess. Using a knife, poke holes in the covering.
Spread the sauce and Parmesan cheese over the top, pinch up the edges and bake at 350°F for approximately 40 minutes.
