Let's cook.
Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
In a large bowl, combine the shredded cooked chicken, cream of chicken soup, milk, frozen mixed vegetables, garlic powder, and black pepper. Stir until well combined.
Pour the chicken mixture into the prepared baking dish and spread it evenly.
Separate the refrigerated biscuit dough into individual biscuits. Arrange the biscuits on top of the chicken mixture, leaving a small space between each biscuit.
Bake for 25-30 minutes, or until the biscuits are golden brown and cooked through, and the chicken mixture is bubbly.
Remove from the oven and let stand for 5 minutes before serving. Garnish with fresh parsley, if desired.
