Preheat the oven to 375°F (190°C).
Sauté the cubed chicken over medium heat until no longer pink, about 5-7 minutes, seasoning with garlic powder, onion powder, salt, and pepper.
Add the frozen mixed vegetables and cook for an additional 2-3 minutes until heated through.
Pour in the cream of chicken soup and chicken broth, mixing until well combined. Allow it to simmer for a few minutes to thicken.
Prepare the Red Lobster Biscuit Mix according to package instructions, typically mixing with water and melted butter.
Pour the chicken and vegetable mixture into a greased baking dish.
Spoon the biscuit batter evenly on top of the chicken mixture.
Bake for about 30 minutes, or until the biscuit topping is golden brown and a toothpick inserted comes out clean.
Let it cool for a few minutes before serving.
