Preheat over to 400 degrees.
Make filling: warm cream cheese in microwave for 30-40 seconds until it is easily stirred. Add artichoke hearts, spinach, and hummus and stir to combine. Season with salt and pepper to taste if desired.
Roll out your sheets of puff pastry to twice its size with a lightly floured rolling pin. And cut it into 18 equal pieces (9 per sheet--most boxes have 2 sheets).
Top each turnover with a heaping spoonful of filling and sprinkling of cheese.
Whisk an egg well and brush on the egg around all edges. Fold over and crimp with a fork.
Slice 2-3 air vents per turnover to allow steam to escape.
Egg wash the tops and top with a sprinkling of cheese.
Bake for 22 minutes until golden and delicious.
