Cut the Brie into thin slices. Wash the peaches, grate them dry, quarter them, remove from the stone and cut the flesh into thin slices.
Remove the dough from the packaging. Unroll with the baking paper directly on a baking tray. Spread a thin layer of crème fraîche. Cover with brie, peach wedges and pancetta. Season with pepper. Bake in the preheated oven (electric cooker: 225 °C/ convection oven: 200 °C/ gas: see manufacturer) for 15-20 minutes.
Meanwhile, clean, wash and shake dry the rocket. Remove the tarte flambée from the oven, sprinkle with honey, cut into 6 pieces and cover with rocket. Garnish as desired with balsamic cream.
