Potato-Rosemary Pizetta

Lightly oil a 17-by-12-inch rimmed baking sheet, and set aside. Roll out dough to a 17-by-12-inch rectangle, and fit into sheet, folding up the edges slightly to form a small lip. Prick dough all over with a fork. Cover with oiled plastic wrap, and let rise in a warm place until slightly puffed, about 30 minutes.

Preheat oven to 450 degrees, with a rack in the center. Place potatoes in a medium bowl and drizzle with olive oil; season with salt and pepper. Distribute potato slices evenly over dough; sprinkle with rosemary and cheese.

Transfer pizetta to oven and bake for 12 minutes. Rotate sheet, and continue baking until crust is golden, about 15 minutes more. Remove from oven; using a large spatula, transfer to a cutting board. Slice into pieces, and serve warm or at room temperature. Although the pizetta is best eaten the day it is baked, it can be reheated the next day; place in a 200 degree oven for 10 to 15 minutes until heated through.
