Preheat oven to 400°F (200°C).
Arrange 3 pepperoni slices, 1 mozzarella cheese slice, 1 tbsp of pizza sauce (in that exact order) on a baking tray lined with parchment paper.
Place an individual, 5 inch, square of puff pastry dough on top of each group of toppings.
Seal the edges of the dough to the parchment paper with your fingers. Brush the top of the dough with egg wash (optional).
Place into oven and bake for 15 mins or until the top is crispy, golden brown
Remove from oven and let it cool for a few mins. Enjoy!
