Unroll the puff pastry on a sheet of baking parchment and cut diagonal strips along the long edges, each strip reaching about 1/3 of the way in towards the centre of the sheet. Do this on both sides.See the photo just below the recipe.
Spread the pizza sauce down the centre, top with half the cheese, then the pepperoni, and finish with the rest of the cheese on top. Scatter a few fresh basil leaves over the filling too, if you like.Season with a little salt, freshly ground pepper and a sprinkling of dried oregano.
Fold the ends of the pastry in over the filling, then fold the strips in over the filling, alternating from side to side – one at a time. See the video above the recipe, if you like.
Brush the top with beaten egg and sprinkle with sesame seeds, then bake the braid in a preheated oven at 200°C, conventional (top and bottom heat), for about 20 minutes.
