In a large mixing bowl, combine all-purpose flour, salt, sugar, and instant yeast. Gradually add warm water and olive oil, stirring until a dough forms. Let it rest for a few minutes.

Transfer the dough to a floured surface and knead for 8-10 minutes until smooth and elastic.

Place the dough in a lightly oiled bowl, cover, and let it rise for 1-1.5 hours until doubled in size.

Cook turkey bacon in a skillet until crispy, then chop and mix with remaining filling ingredients.

Punch down the risen dough, divide into six portions, and roll each into a 6-inch circle.

Spoon filling onto one half of each dough circle, fold over, and seal the edges well.

Beat the egg and brush a thin layer over the top of each calzone.

Preheat air fryer to 375°F (190°C) for optimal cooking.

Place 2-3 calzones in the basket and cook for 12-15 minutes, flipping halfway through.

Remove calzones, let cool slightly, and serve warm.
