Preheat oven to 375°F. Roll dough on lightly floured surface into 17x12-inch rectangle. Spread sauce to within 1 inch of edges; top with pepperoni, sausage and mozzarella cheese.
Fold lengthwise in thirds, slightly overlapping edges in center. Tuck short sides of dough under loaf; pinch all edges together to seal. Place, seam-side down, on large baking sheet sprayed with cooking spray. Make small cuts in top of dough to vent. Brush with oil; sprinkle with oregano and Parmesan cheese.
Bake 25-30 minutes or until golden brown. Cool minutes before cutting into 8 slices to serve.
