Carefully remove skin from chicken thighs in one piece, using a sharp paring knife as needed, and set it aside. You can grind the chicken meat specifically for this recipe or save it for another dish.
In a bowl, combine ground meat, grated garlic, grated cheese, salt, pepper, and water. Mix thoroughly until well combined.
Preheat your oven to 400°F (200°C).
Spread chicken skins, top side down, on a large cutting board. Place 2-3 spoonfuls of stuffing on one side of the chicken skin. Gently pull the edges of the chicken skin over the meat mixture, wrapping it tightly around the stuffing and ensuring the edges overlap for a secure seal. Do not overstuff.
Lay the chicken skins, edges down, on a baking rack inside a baking sheet. Brush with melted or softened butter or ghee and season generously with salt and pepper.
Roast for 25-30 minutes, or until golden and crispy, and the internal temperature of the chicken reaches 165°F.
Carefully remove the cooked ballotines from the baking rack and set them aside to rest, allowing the juices to redistribute. Reserve the flavorful drippings in the baking sheet to use as a rich, savory sauce.
