Preheat the oven to 180°C. Line a baking sheet with parchment paper.
Put the puff pastry onto a large chopping board. Roll it out onto its own wrapping paper.
Cut the sheet into squares, a bit bigger than the diameter of your salami slices. Put a drop of your paste in the middle of the squares and lightly press a basil leaf on it, spreading out the paste. Put a slice of salami/sausage on top.
Place the squares on the baking try, evenly spaced.
Bake for about 10-15 minutes until the puff pastry is golden. Transfer them to a wire rack to cool slightly or completely.
