Preheat oven to 400°F (200°C).

Spray a cookie sheet with nonstick cooking spray.

In a small bowl, toss crumbled feta cheese with most of the red wine vinaigrette, reserving 2 tablespoons.

Unroll refrigerated pizza crust on a cutting board.

Press the crust into a 12 x 12-inch rectangle.

Evenly sprinkle the cheese mixture over the crust.

Roll the crust up tightly, jelly-roll style.

Cut the roll into 1-inch slices.

Arrange the slices, cut side down, on the prepared cookie sheet, about 1 inch apart.

Brush the tops of the slices with the reserved red wine vinaigrette.

Bake for 18 minutes, or until golden brown.

Serve warm.
