Preheat the oven to 400° F
Line a baking sheet with a silicone mat or parchment paper
In your frying pan cook your bacon to your desired doneness & set it aside to cool
In a small bowl mix the cream cheese and chives together.
Grate your favorite cheese or you can use pre-shredded.
Beat one egg in a small bowl for the egg wash.
unroll your sheets of puff pastry and cut into 4 even squares. (These will be folded into triangle shaped pockets)
Put a little of the cream cheese & chives onto each square of puff pastry (saving enough for the four croissants you'll make next)
Top the mixture with your bacon & shredded cheese
brush the edges with the egg wash and fold over and seal them at the edges. I crimped mine using the tines on a fork.
Next roll out your croissants. There are 4 triangles in a roll but I combined two together making four rectangles. Fill them in the same manner as above.
brush the edges with egg wash, fold half over and crimp with your fork.
Bake for 12-15 minutes until golden brown.
Let them cool for a couple minutes, serve, and enjoy
