Place the puff pastry slices next to each other and defrost. Wash the pears, grate them dry, quarter them and cut out the core. Cut 3 pears and gorgonzola into cubes. Chop walnut kernels.
In a pan without fat roast golden yellow and take out. Mix 20 g nuts, gorgonzola and diced pears, season with pepper.
Wash and clean the lamb's lettuce, spin dry and place in a salad bowl. Add pear quarters and the remaining nuts to the salad. Put pear vinegar in a bowl and season with salt and pepper.
Beat down walnut oil.
Place the filling on one half of each slice of puff pastry. Whisk the egg yolks with 1 tablespoon of water. Spread the edges of the pastry with it. Fold the other half of the puff pastry over the filling. Press the edges firmly together with a fork.
Spread the puff pastry pockets with egg yolk and score the top at a slight angle with a knife. Bake in a preheated oven (electric cooker: 175 °C/ convection oven: 150 °C/ gas: see manufacturer) for approx. 20 minutes until golden brown.
Pour the vinaigrette into the salad and fold in. Arrange salad and puff pastry pockets on plates.
