In a large mixing bowl, combine the cooked chicken, mixed vegetables, cream of chicken soup, shredded cheddar cheese, milk, and cooked pasta. Mix well.
Pour the mixture into a baking dish and spread it out evenly.
Bake in the preheated oven for 30 minutes, or until the casserole is bubbly and the top is golden brown.
Let it cool for a few minutes before serving.
Notes:
You can customize this casserole by adding your favorite vegetables or using a different type of cheese.
