Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine shredded chicken, cream cheese, cheddar cheese, green onions, garlic powder, salt, and pepper until well mixed.
Unroll the crescent roll dough onto a clean surface and separate it into triangles.
Place a generous spoonful of the chicken filling at the wide end of each triangle.
Starting from the wide end, roll the dough towards the point, encasing the filling completely.
Place the rolled crescents on a baking sheet lined with parchment paper.
Bake in your preheated oven for 12-15 minutes or until golden brown and flaky.
Remove from the oven and let cool for a few minutes before serving.
