Special equipment: Pasta Machine
Dust 1/2 pound pizza dough with flour; flatten into a rectangle. Roll out with a pasta machine on the widest setting into a 5-by-18-inch sheet, 1/8 inch thick. Halve the sheet crosswise, dust with more flour and cut each half into fettuccine-size strips with the pasta machine. Arrange the strips 1/2 inch apart on parchment-lined baking sheets. Cover with a damp paper towel and plastic wrap and let rise in a warm place until puffed, 60 to 90 minutes. Sprinkle with sea salt and pepper. Bake at 350 degrees F, switching the pans halfway through, until crisp, about 20 minutes.
