Roll out the puff pastry and cut lengthways into approx. 1 cm wide strips.
Halve the slices of bacon lengthways and wrap a strip around a stick of asparagus in a spiral. Now wrap a strip of puff pastry around the asparagus so that it fills the spaces between the bacon. Repeat with the remaining asparagus spears.
Now spread these on a baking sheet lined with baking paper and brush with a whisked egg. Season carefully with salt and pepper and finally sprinkle with black sesame seeds.
Bake in the preheated oven at 200 ° C top and bottom heat for 18 minutes.
