Preheat oven to 375F. Cut each puff pastry sheet into fours so that you have 8 squares total. Add about 1 tablespoon of sun dried tomato paste to each square and smear it evenly in the middle of each square. Add a piece of prosciutto on top followed by a few stalks of asparagus. Crumble a little bit of goat cheese on top of asparagus.
Carefully fold each puff pastry in the middle so it looks like its hugging the asparagus. Brush whisked egg white over each puff pastry and put a little underneath the flap to help it stay in a bundle shape.
Evenly space the puff pastries around the baking sheet and sprinkle each one with a few pinches of herbs de provence and some flaky salt. Bake for 20-22 minutes or until each puff pastry is golden brown and the asparagus is cooked. Remove from heat and enjoy warm or at room temp.
