Preheat your oven to 400 degrees
Unroll the pizza dough and roll it out on a clean surface using a rolling pin to make it an even layer.
Using a knife or a pizza cutter, cut out squares about 3x3 inches. You will need 29 pieces of dough to make the tree.
Using a paper towel, dry off the bocconcini. Wrap each one in prosciutto and enclose in the dough, rolling to seal the edges.
Arrange the balls on a parchment lined baking sheet into a tree shape
Brush with the beaten egg, and then sprinkle generously with oregano, garlic powder and cheese.
Bake for 20-25 minutes, or until the tree has developed some color.
Broil for 2 minutes for some extra browning.
Decorate and enjoy!
