How to make
Roll out the puff pastry on the kitchen counter and cut it into whatever shapes you like (into squares, circles, etc.).
In a muffin tin greased with butter, place the squares by lightly pressing them down and placing the thinly sliced fillet in each one.
Cut the processed cheese into large cubes and add 2-3 pickles at the end.
Beat the egg and spread it on the edges and bake the puff pastry in a preheated oven at 360°F (180 degrees).
The incredibly delicious puff pastries are ready.
