Nutella & Banana Pockets

Preheat oven to 450 degrees. Dust surface lightly with flour. Divide dough into 8 balls; roll into 4-inch rounds. Transfer to a rimmed baking sheet. Let stand, draped with plastic, in a warm place until they double in size, about 30 minutes.

Lightly brush with egg. Bake until golden, about 8 minutes. Let cool slightly. Use a knife to slice pita-like pockets; stuff each with 1 tablespoon Nutella and 4 slices banana. Serve immediately.
