Preheat your oven to 400 degrees F (200 degrees C) and position the rack in the center. Line a baking sheet with parchment paper.

Roll out the pizza dough on a floured surface into a large triangle shape resembling a Christmas tree.

Spread the Alfredo sauce evenly over the dough triangle and lay the mozzarella cheese sticks horizontally across the dough, leaving some space between each.

Fold the dough over the cheese sticks from both sides and press to seal, shaping it into a Christmas tree form, trimming edges if necessary.

Brush the entire surface with olive oil and sprinkle the Italian herbs evenly.

Spoon the pesto sauce over the tree and sprinkle shredded mozzarella cheese over the top. Decorate with sliced green bell pepper, halved cherry tomatoes, and mini pepperoni slices.

Place the prepared pizza tree on the lined baking sheet and bake for about 25 minutes, until the crust is golden brown and the cheese is melted and bubbly.

Remove from oven, sprinkle with grated Parmesan cheese, let cool slightly, and then slice and serve warm.
