Preheat oven to 425 degrees F. Lightly oil a 24-cup mini muffin tin or coat with nonstick spray. In a small bowl, whisk together butter, garlic, oregano, basil and salt; set aside. Halve each of the 8 biscuits, making 16 pieces. Working one at a time, use a rolling pin to flatten each piece to about 1/4-inch thickness. Add 3 mozzarella pearls to the center of each biscuit piece before rolling into a ball. Place into the prepared muffin tin and brush each ball with half of the butter mixture; sprinkle with Parmesan. Place into oven and bake until golden brown, about 8-10 minutes. Serve immediately, brushed with remaining butter mixture and garnished with parsley, if desired.
