In a large skillet, heat olive oil over medium heat. Add the shredded chicken and the frozen mixed vegetables. Sauté for about 5 minutes until the vegetables are tender.
Pour in the chicken broth and stir in garlic powder, onion powder, dried thyme, and black pepper. Let it simmer for another 3-4 minutes until slightly thickened. Remove from heat and set aside.
In a separate bowl, combine the flour and baking powder. Add the milk and mix until just combined; do not overmix.
In a greased baking dish, pour the chicken and vegetable mixture evenly across the bottom.
Drop spoonfuls of the batter over the chicken mixture, covering it as much as possible. Sprinkle the shredded cheese on top of the batter.
Bake in the preheated oven for 20-25 minutes or until the top is golden brown and a toothpick inserted into the batter comes out clean.
Once baked, remove from oven and let it cool for a few minutes before serving. Garnish with freshly chopped parsley.
Notes
Serve hot directly from the baking dish or scoop individual portions into bowls. Add an extra sprinkle of parsley and a wedge of lemon on the side for a pop of color!
