Combine the yeast and lukewarm water and let sit for 5 minutes.

In a large bowl or the bowl of your stand mixer fitted with a kneading hook, combine 1 cup of the flour and the cornmeal. Add the yeast mixture, olive oil and honey. Stir until moistened. Add more flour in small increments, until you achieve a soft dough that is neither too sticky or too stiff. Remove the dough to a well-oiled large bowl and let rise at room temperature for 1 hour.

While dough is rising, cook your sausage. If your sausage is links in casing, cut a slit down the casing and remove the sausage from the casing. Discard casing. Cook sausage in a skillet, breaking up into small pieces with a spoon, until cooked and browned. Turn off heat under skillet and set aside until needed. 

Preheat oven to 425° F. Grease the bottom and sides of cast-iron frying pan with olive oil and lightly dust with additional cornmeal.

When dough is ready, scrape onto a well-floured surface (dough will seem sticky at this point, but will be fine with the additional flour on the counter. With a rolling pin, roll dough into a circle a little bigger than the bottom of your skillet. If it's sticky, dust with more flour as needed. Transfer the dough to prepared cast-iron frying pan and press into bottom and up the sides about ⅔ of the way up. Cover the bottom of pizza completely with a generous layer of mozzarella cheese. Top with cooked sausage. Top with all of the pizza sauce, spreading it to cover the sausage. Sprinkle the top generously with freshly grated Parmesan cheese. *You don't want your crust to extend too much higher than your filling, or the exposed part at the top will overcook. If it extends too high once your filling is in, push or crimp it down to closer to the level of your filling.

Bake in pre-heated 425° F. oven for about 20 minutes. Check at 20 minutes and if crust is dark enough (it usually is at this point), cover loosely with a sheet of tinfoil and cook about at least 10 minutes longer or better yet, 13-15 minutes more (33-35 minutes total), to be sure the crust is cooked.

Remove from oven and allow to cool in the pan for 10 minutes. Using a spatula, carefully remove pizza to a cutting board. Allow to stand a couple more minutes before cutting with a sharp knife.
