Preheat your oven to 190°C (375°F) and line a baking sheet with parchment paper.

In a medium bowl, combine the cooked chicken, Alfredo sauce, shredded mozzarella, grated Parmesan, garlic powder, and black pepper. Stir well until mixed.

Unroll the crescent roll dough onto a clean surface and cut into individual triangles as per package instructions.

Place about 2 tablespoons of the chicken mixture at the wide end of each triangle and roll towards the tip, sealing the filling inside.

Bake for 12–15 minutes or until golden brown, keeping an eye on them.

Let cool slightly before serving, and garnish with chopped parsley if desired.
