Preheat oven to 400 degrees, and lightly coat a baking dish with cooking spray.

In a food processor, combine cream cheese, spinach, mozzarella, artichoke hearts, and one clove of garlic; pulse until combined.

Divide pizza dough into about 15 pieces and roll out each piece into a disc.

Scoop about a tablespoon of the spinach-artichoke filling into each dough disc and loosely pinch the sides together before placing them in the prepared baking dish. Repeat until all pieces have been stuffed with the remaining spinach-artichoke mixture.

Mince the remaining garlic clove and combine it with the melted butter; use a pastry brush to spread the melted butter and garlic over the top of the stuffed dough.

Bake for 25-30 minutes until the filling is bubbling and the dough is cooked. Season with fresh ground black pepper before serving.
