Pre-baking the dough keeps it from getting moist and soggy.
It is possible to prebake the base a day ahead and to keep it at room temperature before finishing.
For pinwheels, roll the dough in a rectangle, fill it with sauce and very finely chopped vegetables. Roll it into a long cylinder and cut into spirals. Put cut side down on the tray, sprinkle with cheese, let proof and bake.
This quantity will feed 10 people or make about 20 pinwheels
Choose sauce and vegetables to your liking.
