Preheat oven to 400.
In a medium skillet heat a teaspoon of olive oil over medium heat.
When hot, add spinach and cook until wilted and hot.
Squeeze out moisture and chop spinach.
In a large bowl combine spinach, cream cheese, sour cream, 1/2 teaspoon minced garlic, salt, pepper, 1/2 cup parmesan cheese and the mozzarella cheese until combined.
Set aside.
First, roll out your pizza dough and cut a large triangle out of it. This will leave you with one large triangle and two smaller ones.
Leave the large triangle on some parchment paper and transfer the two smaller ones to a greased or parchment-lined baking sheet. We're going to pinch these two smaller triangles together to form the base of our tree. It doesn't have to look pretty- this is going to be the bottom.
Evenly spread the prepared spinach dip over this triangle.
Distribute 1/4 cup of shredded Parmesan over spinach dip.
Now take that larger triangle from earlier and place it over our dip-covered tree.
Use a pizza cutter to start cutting 1" wide strips on each sidee. You'll likely end up making about 11 branches here. Make sure you don't cut through the center.
Give each branch a twist.
Bake at 400 for 10 minutes.
Rotate sheet and bake another 6 minutes.
In a small bowl, combine the melted butter and 1/4 teaspoon of minced garlic. Mix to combine.
Brush the tree with the garlic butter mixture.
Sprinkle with the remaining shredded parmesan.
Return to oven to cook until golden brown (about 3 minutes).
