Sift self-raising flour and a pinch of salt into a bowl and make a well in the centre.

In a separate bowl beat together egg, olive oil and milk and stir into self-raising flour, mixing all ingredients into a soft dough.

Turn mixture out onto a floured surface and knead lightly.

Divide the dough into 3 - the calzones turn out quite large so 1 quantity is probably enough for 2 adults and 2 little kids (1 shared between the kids).

With the heel of your hand flatten each portion of dough to roughly 1.5cm thick and stretch into an oval. Top half the oval with your favourite toppings leaving a 1 cm gap around the sides.

When you're done, fold the other half over the toppings creating a parcel and pinch right round to seal. Prick the top a couple of times with a fork to let some steam out. Bake in a preheated oven at 200ºC for 15-20 minutes.
