  Preheat oven to 500 degrees with rack in center. Place 12-inch cast-iron skillet in preheated oven 10 min. Remove skillet carefully from oven using oven mitts; set on heat-safe surface. Brush skillet carefully with remaining olive oil. Shape dough ball on lightly floured surface into 12-inch round, pressing out any air bubbles. Transfer to skillet carefully; form to fit bottom of skillet.

  Brush crust evenly with basting oil; top with 1 Tbsp grated cheese and mozzarella. Break ricotta into smaller pieces; sprinkle evenly on crust. Top crust with cooked spinach; sprinkle with garlic powder and remaining grated cheese.

  Bake 12-15 min. Remove skillet carefully from oven using oven mitts; transfer pizza to cutting board with spatula. Slice.
