Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a mixing bowl, combine the shredded chicken, cheddar cheese, cream cheese, and green onions (if using). Season with salt and pepper to taste.
Open the can of crescent roll dough and separate into the pre-cut triangles.
Spoon a generous amount of the chicken and cheese mixture onto the wide end of each triangle.
Roll up each triangle starting from the wide end to the point, ensuring the filling is enclosed.
Place the filled crescents onto the baking sheet, leaving space between each one.
Bake in the preheated oven for 12-15 minutes, or until the rolls are golden brown and the cheese is melted.
Let cool slightly before serving.
