Preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper. Separate the 8 biscuits and cut each one into quarters.

Take a small pinch of the shredded mozzarella and press it into the center of each biscuit quarter, then roll the dough around the cheese to form a small ball. Ensure it's sealed well.

Arrange the dough balls on the prepared baking sheet in the shape of a football. Pack them closely together so they will bake into one pull-apart loaf.

In a small bowl, mix together the melted butter, garlic powder, and dried parsley. Brush this mixture evenly over the top of the football-shaped dough. Sprinkle with Parmesan cheese.

Bake for 18-20 minutes, or until the top is golden brown and the dough is cooked through.

Let the bread cool for a few minutes. While it's still warm, cut the string cheese into thin strips and arrange them on top to look like football laces. Serve warm with marinara sauce for dipping.
