Optional garnishes: crushed red pepper flakes, sliced or chopped fresh basil
Let pizza dough stand on a floured surface 15 minutes.
Heat oil in a deep 12-inch heavy skillet or electric skillet over moderate heat until oil registers 350°F on thermometer or dial of electric skillet.
Roll out and stretch dough with floured hands, pressing on work surface, to form a 10-inch round (don't worry if it is irregularly shaped). Fry dough, turning once, until golden brown and slightly puffed, 2 to 3 minutes per side. Transfer to a parchment-lined baking sheet. (Fried dough can stand at room temperature up to 1 hour before topping and baking.)
Spread pizza sauce over fried dough; top as desired. Sprinkle cheese evenly over pizza. Bake in a preheated 375°F oven 12 to 14 minutes or until cheese is melted. Cut into wedges; garnish as desired.
