Defrost the puff pastry sheets, place them on top of each other and roll out to a thickness of approx. 4 mm. Cut out approx. 12 circles with a round cookie cutter (4.5 cm Ø) and place them on a baking tray lined with baking paper. Grate the cheese finely and spread on the puff pastry. Roast sesame seeds in a dry pan until golden brown and sprinkle over the cheese. Bake in the preheated oven (electric cooker: 200 °C/ gas: level 3) for 15-20 minutes.
Leave to cool. In the meantime, peel, wash and dice the potatoes. Clean carrots, cauliflower and leek. Peel carrots and cut into longish pieces. Wash the cauliflower and cut into florets.
