Roll out the puff pastry and cut into 6 equal-sized rectangles. To do this, cut the dough once vertically and twice horizontally.
Place the pieces on a baking tray lined with baking paper and brush with whisked egg yolk. Place a slice of ham on each part. Spread the sliced tomatoes on top. Season with herb salt and pepper.
Divide the camembert into small pieces and place a piece of camembert on each tomato slice.
Bake everything in the preheated oven at approx. 180 ° convection for 15-18 minutes. The puff pastry should be golden brown and the cheese can also have some color.
Arrange everything on plates and decorate with the chives rolls.
