Preheat oven to 375°F (190°C). Cut pizza dough into 1-2 inch pieces and roll into balls.
In a bowl, combine melted butter, garlic, and salt. Arrange dough balls into a tree shape on a baking sheet, brushing with garlic butter and sprinkling with mozzarella.
Bake for 20-25 minutes or until golden brown and cheese is bubbling.
Garnish with chopped parsley and Parmesan. Serve warm with dipping sauces if desired.
