1. Preheat the oven to 400°F. Line a baking sheet with parchment paper or a nonstick baking mat.

2. Lightly flour a clean countertop. Place the pizza dough on the surface and gently press it into a rectangle shape. Using a floured rolling pin, roll the dough into a thin rectangle about 10 inches tall and 16 inches wide.

3. Spread the tomato sauce evenly over the dough, leaving a 1-inch border along the top edge.

4. Sprinkle the mozzarella cheese evenly over the sauce. Add the turkey pepperoni, red onion, and basil across the surface.

5. Starting from the long edge closest to you, tightly roll the dough into a log. Pinch the seam closed at the top.

6. Using a sharp knife, slice the roll into 12 equal pinwheels. Transfer them to the prepared baking sheet, spacing them a few inches apart.

7. For softer, fluffier pinwheels, let them rise at room temperature for 30 to 45 minutes before baking. Otherwise, bake immediately.

8. Bake for 12 to 15 minutes, or until the cheese is melted and bubbly and the tops are golden brown.

9. Let the pinwheels cool for a few minutes before serving. Garnish with extra fresh basil if desired.
