Preheat oven to 220°C. Line two baking trays with baking paper.
Whisk 1 cup warm water with yeast and sugar in a jug. Stand for 10 minutes until mixture is frothy.
Place flour and salt into a bowl. Add oil to yeast mixture and stir to combine. Pour into flour and mix well to form a dough. Set aside for 5 minutes.
Divide dough into 4 even portions. Roll out each portion on a lightly floured surface to a 24cm round. Divide the salami, artichoke, tomato, cheese and spinach over one half of each dough round, leaving a 2cm border. Brush border with water, then fold dough over the filling. Press edges together to seal and transfer to prepared trays. Brush tops with egg. Sprinkle with salt and pepper. Bake for 15 minutes or until golden and crisp. Slice in half. Serve with mixed green salad.
