Unwrap both of the puff pastry doughs and cut into 8 squares (4 from each dough).
Place a heaping tablespoon or two of cherry pie filling in the center of each square. Brush the edges of the squares with the egg white and fold over to enclose the pie filling.
Bake on an un-greased baking sheet for 20 to 25 minutes, or until puff pastry is golden brown.
Let cool on a wire rack.
To make vanilla glaze:
Combine the powdered sugar, milk and vanilla extract in a bowl and whisk until smooth. Pour in a frosting bag or zip close bag then snip off the tip or corner to pipe on the cooled turnovers. Enjoy!
Notes
You can use any type of pie filling in place of the cherry. Or, use a tablespoon of Nutella for a chocolate turnover!
