Remove puff pastry sheets from package and lay on counter to thaw. In the meanwhile chop strawberries into small pieces and place in a bowl. Toss with granulated sugar and let sit for 30 minutes.
Pre heat oven to 400 degrees. Lightly flour your work surface and unfold pastry sheets and cut along the creases to create 6 long strips of dough. On one half of the dough gently spread 1 tbsp of cream cheese in the center(you should only use about 3oz of the cream cheese and leave the remaining 1oz for the glaze), leaving about an inch of dough on each side. Top with 1-2 tbsp of chopped strawberries. Fold the dough over, and pinch closed with a fork to create an enclosed pocket. Repeat for all 6 pastries.
Place on a parchment or silicone lined baking sheet. Beat the egg with 1 tbsp of water in a small bowl. Brush the tops of the pastries with the egg wash. Using a sharp knife cut 3 slices on the top of the pastry, being careful not to slice through the bottom.
Bake for 15-16 minutes. Should be puffed up and a golden brown.
To make the glaze, in a small bowl combine the remaining 1oz of cream cheese with 1/2 cup powdered sugar and 1 tsp of milk or heavy cream and beat with a fork or whisk until smooth. Spoon into a zip close bag and snip a corner off to pipe onto a warm 'toaster' strudel.
