Preheat your oven to 375°F (190°C).
In a large mixing bowl, combine shredded chicken, cream cheese, cheddar cheese, garlic powder, onion powder, salt, and pepper.
Unroll the crescent roll dough and separate it into triangles.
Place a spoonful of the chicken mixture at the wide end of each triangle.
Roll each triangle tightly from the wide end to the point.
Arrange crescents on a baking sheet lined with parchment paper.
Bake for 12-15 minutes or until golden brown.
Remove from the oven and let cool slightly before serving.
