Allow pizza dough to rest, covered, at room temperature for 45 minutes.
Preheat your oven to 500°F (260°C).
Spray a rimmed baking sheet (13x18 inches) with nonstick spray and sprinkle with cornmeal.
In a food processor, blend drained tomatoes, olive oil, vinegar, garlic, salt, sugar, oregano, red pepper flakes, and black pepper for 30 seconds.
Roll pizza dough into a rectangle and press into the prepared baking sheet.
Spread tomato sauce evenly over the dough.
Sprinkle mozzarella cheese over the sauce, then arrange pepperoni on top.
Bake for 16-18 minutes, or until the crust is golden and cheese is melted.
Garnish with fresh basil, if desired.
Slice into 8 pieces and serve immediately.
