We divide the puff pastry into two halves and roll each of them into rectangles with a size of about 20x30 cm. Then we smear them with ketchup, on which we place whole slices of ham. Sprinkle the ham with grated cheese. We roll up the rectangle like a roll, which we cut into centimeter wheels and place them on a baking sheet lined with baking paper. Brush the snails with a beaten egg (around the perimeter) and sprinkle the pizza with pepper.

Bake the snails in an oven heated to 180 degrees Celsius for approximately 20-25 minutes.
