preheat the oven to 200C/Gas 6, 15 minutes before baking; lightly oil a large baking sheet
roll the prepared pastry out to a 23cm round and place the pastry round on to the baking sheet and crimp the edges; prick all over with a fork and chill in the fridge for 30 minutes
line the pastry with foil and weigh down with an ovenproof flat dinner plate or base of a large flan tin and bake blind in the preheated oven until the edges begin to colour; remove from the oven and discard the weight and tinfoil
carefully spread the chocolate spread over the pizza base and arrange the peach slices around the outside edge in overlapping circles; toss the berries with the plain chocolate and arrange in the centre; drizzle with the melted butter and sprinkle with the sugar
bake in the preheated oven for 10-12 minutes or until the fruit begins to soften; transfer the pizza to a wire rack
sprinkle the white chocolate and hazelnuts over the surface and return to the oven for 1 minute or until the chocolate begins to soften; if the pastry starts to darken too much, cover the edge with strips of foil; remove to a wire rack and leave to cool; decorate with the mint sprigs and serve warm
