Preheat oven to 350°F. Meanwhile grate 8 ounces of mozzarella cheese on the large holes of a box grater. (Note: It's best to grate an 8-ounce chunk of cheese instead of using pregrated -- pregrated is coated with cornstarch to keep it from clumping, and that affects even melting.)
Make a chiffonade of fresh basil using about 6 large leaves.
Cheese and Repeat
Repeat process with second portion of dough, remaining sauce, another dusting of Parm, and the remaining mozzarella. Add some more basil.
Bake, Cool, Tear Apart
Pro tip: Make sure to provide your kids with plenty of napkins.
