" Preheat oven to 400 degrees F. Remove frozen spinach from package. In small microwave-safe bowl, heat spinach in microwave oven on High 2 to 3 minutes or just until spinach is mostly thawed but still cool enough to handle. Squeeze spinach to remove excess water. Meanwhile, in small bowl, combine ricotta, mozzarella, cornstarch, and oregano; set aside. Spray large cookie sheet with nonstick cooking spray. Unroll pizza dough on center of cookie sheet. With fingertips, press dough into 14- by 10-inch rectangle. Spread cheese mixture lengthwise on half of dough, leaving 1-inch border. Spoon marinara sauce over cheese mixture; top with spinach.
