Grease an 8- or 10-inch cast iron skillet. Remove the thawed pie crust from the tray and line the skillet with it. Tuck ½ inch of the dough underneath itself to form an edge. Prick the bottom of the crust in several places with a fork. Place a double layer of tin foil in the crust, line with pie weights or dried beans and bake for 25-30 minutes or until pale brown. Remove the skillet from the oven, carefully remove the pie weights and foil, and reduce the oven temperature to 350.
In a large mixing bowl, whisk together the eggs, half-and-half, cheese, salt, and pepper.
Place the cherry tomato halves in the bottom of the pie crust. Pour the egg mixture over and bake for 35 minutes or until set. Let cool 5 minutes before serving.
