Roll out the puff pastry and place on a baking sheet.
Wash the peppers and cut into small cubes. Fry in a little hot oil, season with salt and pepper. Season the minced meat with salt, pepper, paprika and herbs and spread about 2 cm thick on the puff pastry. Leave about 2 cm of space at the edge. Then spread the pepper pieces on top. Place the Emmental cheese cut into cubes on top.
Now everything is formed into a roll. The ends should be closed so that nothing leaks out. Brush the puff pastry with the egg yolk. Place on a lightly greased baking sheet and bake in the oven (top and bottom heat) at 180 ° for about 1 ½ hours.
