Preheat the oven to 375°F (190°C) and line a baking sheet with parchment paper.
Combine the melted butter with the garlic and parsley, and stir to mix well.
Unroll the crescent rolls and separate them into triangles. Place a string cheese horizontally at the bottom of each triangle, fold in the sides, and roll up to form croissant-shaped rolls. Brush the tops with the garlic herb butter.
Bake for 10 minutes, or until they are lightly browned. Serve immediately.
