- 2 bunches spinach (1 pound, 6 ounces), tough stems trimmed, washed, with water still clinging to leaves
- Extra-virgin olive oil, for brushing
- Unbleached all-purpose flour, for dusting
- 1 pound store-bought pizza dough, divided in half
- 8 ounces low-moisture mozzarella, such as Polly-O, thinly sliced
- 2 ounces feta, crumbled (1/3 cup)
- Kosher salt
- Pinch of red-pepper flakes
- 1 large egg, beaten
- 1 tablespoon sesame seeds
Place spinach in a large pot over high heat; cover. Steam until just collapsed, about 3 minutes; transfer to a colander. When cool enough to handle, squeeze out excess water; roughly chop.
Preheat oven to 425 degrees, with a rack in lower third. Brush a 9 1/2-by-13-inch rimmed baking sheet with oil. On a lightly floured work surface, roll out and stretch one piece of dough into a thin 10-by-13-inch rectangle. (If dough is springing back, let stand 5 minutes.) Transfer to prepared baking sheet. Arrange mozzarella over dough, leaving a 1-inch border. Top with spinach and sprinkle with feta. Season with salt and red-pepper flakes. Roll out and stretch remaining portion of dough into a 10-by-14-inch rectangle. Drape over filling. Pinch edges to seal; slash a few vents in top. Brush with egg wash; sprinkle with sesame seeds.
Bake until golden brown all over and filling is bubbling through vents, 40 to 45 minutes. (Check color of bottom crust by lifting corner with a spatula.) Immediately slide pie off sheet onto a wire rack. Let cool completely. Before serving, cut into squares.
Letting the pie cool on a wire rack keeps the bottom crust from getting soggy. Once it's cool, return it to the baking sheet for transport.
