Lightly flour a work surface. Use a rolling pin to roll out the biscuit to 1/8" thickness. Add a heaping tablespoon of the broccoli mixture to the biscuit.
Brush the egg wash along the edge of the biscuit then fold together and seal. Use a fork to press the edges together. Place the pie on a baking sheet lined with parchment paper. Repeat until you have 8 pies.
Bake 10-14 minutes or until the biscuits are golden brown.
