Cook the broccoli in boiling salted water for 3 minutes.
Drain and chop.
In a large skillet, heat the olive oil.
Add the garlic and cook over moderate heat until fragrant, about 30 seconds.
Add the tomatoes, olives and red pepper and cook for 1 minute.
Add the broccoli; season with salt and pepper.
On a lightly floured work surface, roll each piece of dough into a 12-by-9-inch rectangle. Spoon half of the broccoli mixture down one longer side of each rectangle, about 2 inches from the edge. Top each with half of the feta and Parmesan.
Roll the dough up around the filling; fold in the sides.
Bake for about 40 minutes, or until brown.
Let cool slightly; then slice and serve.
Serve with salad. For a heartier dish, roll pepperoni slices into the dough.
