Preheat the oven to 375°F (190°C).

In a mixing bowl, combine the shredded chicken, cream cheese, cheddar cheese, green onions, garlic powder, and onion powder until well blended.

Using a can of crescent roll dough, unroll it and separate it into triangles along the perforations.

Place a generous tablespoon of the chicken filling at the wide end of each triangle.

Roll the dough from the wide end to the pointed end, creating a sealed pillow.

Arrange the rolled pillows on a baking sheet lined with parchment paper, leaving space between each.

Brush the tops of the pillows with a beaten egg for a shiny finish.

Bake in the preheated oven for 15-20 minutes, or until golden brown.

Remove from the oven and let cool slightly before serving.
