Cut the salami, onion and camembert into small cubes. Drain the mushrooms from the glass, add and add an egg. Season the ingredients as you like, e.g. with salt (be careful, salami and cheese are salty!) And pepper, mix everything carefully and let it steep for about 10 minutes.
Meanwhile preheat the oven to 180 ° and cut the rolls. Then distribute the ingredients evenly on the roll halves and place in the preheated oven for about 10 minutes. The rolls are ready when the camembert has melted.
