"homemade" pizza pockets

tweaked from MckMama's recipe

INGREDIENTS
at least 2 refrigerated pie crusts
spaghetti sauce
fresh mozzarella (I used shredded)
pepperoni (I used turkey pepperoni)
egg white (which I forgot!)

1. preheat oven to 350 degrees.
2. Bring pie crusts to room temperature. Unroll pie crusts and cut into 3 semi-equal sections. (do NOT defrost in microwave....it just makes it a MESS and leads to very ugly and frustrating pizza pockets....TRUST ME, I know!) I put them directly onto a greased cookie sheet. You could also put them onto a cutting board or a clean countertop to work.
3. Spoon and spread a few scoops of sauce on crusts....make 1 "stripe" down the middle of each section.
4. One one 1/2 of a section sprinkle a small handful of cheese and then place pepperonis on top of cheese.
5. Fold the other end of the  strip over the toppings and press the open edges closed. If needed fold over the edges to seal the pocket.  (This is when I should have brushed with egg white, had I remembered) Poke each section 2 or 3 time with a knife to vent.
6. Bake until golden brown,  about 30 minutes.

Variations to try: other ingredients....also curious to try  using refrigerated cresecent roll dough as the crust.
