Preheat the oven to 450°F. Cut each mozzarella stick into 5 pieces.
On a floured surface, divide each batch of pizza dough in half and roll each piece into an 18" x 4" rectangle.
Cut the dough into 2" squares (you’ll need about 33). Wrap each square around a piece of cheese and seal well.
Arrange the dough balls seam-side down on a parchment-lined baking sheet to form a Christmas tree.
Whisk the egg with 1 tbsp water and brush lightly over the dough balls.
Bake for 15–20 minutes, or until golden brown.
Mix melted butter with parsley, basil, and rosemary. Brush over the warm tree and garnish with extra herbs or red pepper flakes.
Serve warm with marinara or your favorite dip.
