Sprinkle a work surface with flour and divide the dough in half. With a rolling pin, roll out dough to two 8-inch circles, approximately ⅛-inch thick. Carefully lift the dough directly onto the grill rack. Brush olive oil lightly over the top side of each crust. Grill about 2 minutes, until the dough bubbles and begins to char on the bottom. Turn over.
Evenly distribute half of the cheese and pear slices over each crust. Close the grill cover or tent with foil. Grill 3 to 5 minutes, until the cheese is melted and the crust is crispy.
Remove from the grill, cut into wedges and serve.
Notes
If you cannot locate fresh pizza dough and don't wish to make it yourself, try visiting your local pizza establishment and ask if they will sell a ball of fresh dough to you- they often will!
