Place the puff pastry on a parchment-lined baking sheet.
Pour the herb quark into a bowl and season with salt, pepper and paprika powder. Pour half of this mixture onto the puff pastry, spread it out well, leaving approx. 1 cm free from the edge. Now distribute the salmon evenly on top. Now put the rest of the quark mixture on top and spread it evenly again. Now roll up the puff pastry and brush with a little water.
Bake in the preheated oven at 200 ° C hot air for about 30 minutes (depending on the desired tan). Slice and serve immediately.
