Easy & Warm pastry puff meal

My little sis is quite the chef.  She always creates healthy and hearty recipes all on her own.  I thought i'd share one of her latest creations (since she swears it's so easy).
  She Writes: I just made the easiest, BEST dinner ever!  I thawed puff pastry and added diced turkey breast (raw - it bakes in the oven), minced garlic, s&p, a little feta, some sun dried tomatoes, and a huge handful of fresh spinach! Then I just sealed it in a pouch and put an egg wash over it and it was done in 37 mins at 375 degrees!! :)  
Thanks Bren- can't wait to try this with chicken too.
