Pre-heat oven to 400 degrees F.
Heat a medium skillet and add ground sausage to skillet. Use a spatula to break apart ground sausage into small pieces. Cook until it is no longer pinkish.
Turn off heat and add shredded cheese to skillet. Mix to combine. Cheesy do not have to be completely melted.
Cut each defrosted puff pastry sheet into 9 squares of the same size
Fill them with ~2 tbsp of meat. Spread the meat across two opposite corners of the square.
Break an egg into a small bowl and whisk the egg.
Wrap up pockets by folding in the other two opposite corners. Place on corner on top of the other, and use egg wash to seal corners together. Remember to press gently to make sure it seals. They do open up easily during baking if not sealed well.
Brush the top of the pockets with more egg wash
Set pockets on a baking sheet lined with parchment paper or baking mat. If not, grease baking sheet.
Bake for 15-18 minutes.
Remove and cool for a few minutes. Serve and enjoy!
