1Preheat your oven to 400°F (200°C).
In a skillet over medium heat, cook the bulk mild Italian sausage until browned and fully cooked. Drain any excess fat.
In a mixing bowl, combine the cooked sausage with the cream cheese until well blended.
Roll out the puff pastry sheet on a lightly floured surface to smooth out any creases.
Cut the puff pastry into 24 equal squares.
Place a small spoonful of the sausage and cream cheese mixture onto the center of each puff pastry square.
Sprinkle a small amount of shaved Parmesan cheese on top of the sausage mixture.
Fold the corners of each puff pastry square over the filling and pinch to seal.
In a small bowl, beat the egg and brush it over the tops of the puff pastry bites.
Sprinkle the black pepper over the tops of the bites.
Place the puff pastry bites on a baking sheet lined with parchment paper.
Bake in the preheated oven for 15-20 minutes, or until the pastry is golden brown and puffed.
Remove from the oven and let cool slightly before serving. Enjoy your Italian Sausage Puff Pastry Bites!
