In a large mixing bowl, combine the flour and salt. In a separate small bowl, sprinkle the yeast into warm water and let sit for 5 minutes until frothy. Pour the yeast mixture into the flour mixture and stir until a sticky dough forms.

Turn the dough onto a floured surface and knead for about 10 minutes until smooth and elastic. The dough should be slightly tacky but not sticky.

Shape the dough into a ball, place it in a greased bowl, and cover with a damp cloth. Let it rise in a warm spot for about 1 hour, or until doubled in size.

Preheat your oven to 220°C (430°F). Line a baking sheet with parchment paper and set aside.

Punch down the risen dough gently to release air, then divide it into 4 equal portions. Roll each portion into a thin circle about 6 inches in diameter.

Place a generous spoonful of cheese, pepperoni, and vegetables on one half of each circle, leaving a small border around the edges.

Fold the dough over the filling to create a semi-circle, then pinch and seal the edges tightly to prevent filling from leaking out.

Use a pastry cutter or sharp knife to carefully cut out bat wings and ears from the edges of each calzone, shaping them into fun, spooky forms.

Arrange the shaped calzones on the prepared baking sheet. Brush the tops with beaten egg to give a shiny, golden finish.

Bake for 15–20 minutes, or until the calzones are crispy, puffed, and golden brown around the edges and shapes.

Remove from the oven and let cool slightly before serving. These fun calzones are perfect for a spooky snack or party treat!
