1Preheat oven to 400 degrees F. On a lightly floured surface, roll out pizza dough into 15- x 12-inch rectangle. Transfer to a large greased baking sheet.
2Spread pizza sauce evenly over dough, leaving 1-inch border all around. Top with 1 cup mozzarella and 1 cup provolone cheese.
3Slice sausages into 1/2-inch pieces. Top pizza with sliced sausages, onion, red pepper, green pepper, garlic, sun-dried tomatoes and chili flakes. Sprinkle with remaining cheese.
4Bake for 18 to 20 minutes or until dough is golden and crisp, vegetables are tender, and cheese is melted.
5Scatter pepperoncini over top; drizzle with oil. Sprinkle with basil.
6Tip: Substitute Polish, Hot Polish or Beef Polish for Hot Beef Polish Sausage.
