Method

1. Prepare your campfire by ensuring you have hot embers or a bed of coals. You want consistent heat, not flames.
2. Spread out the pizza dough into a large circle on a cast-iron skillet.
3. On one half of the dough circle, layer slices of ham and a generous amount of shredded cheese.
4. Spoon a dollop of passata or tomato sauce over the ham and cheese layer.
5. Fold the other half of the dough over the toppings to create a half-moon shape. Press and seal the edges firmly to prevent any filling from leaking out during cooking.
6. Lightly brush the sealed calzones with olive oil. This will help create a nice crust while cooking.
7. Top with a lid and cook for about 5-8 minutes per side, rotating occasionally, until the dough is golden brown and the cheese is melted and bubbly.
8. Remove from the heat and let cool slightly before serving.
