Preheat your oven to 375°F (190°C).
In a mixing bowl, combine the shredded chicken, cream of chicken soup, cheese, and mixed vegetables (if using). Season generously with salt and pepper.
Roll out the crescent roll dough and place it in a greased baking dish, ensuring it covers the bottom and sides well.
Spoon the creamy chicken mixture into the dough-lined dish.
Roll out the remaining crescent rolls on top of the filling to create a delightful lid.
Bake in the preheated oven for 25-30 minutes or until the crescent rolls turn a beautiful golden brown.
Let it cool for a few minutes before diving in—enjoy every comforting bite!
