Southern Chicken and Dumpling Soup

2 tablespoons butter
1 medium onion, chopped
2 garlic cloves, minced
1/2 cup celery, diced
1/2 cup carrots, diced
6 cups chicken broth
2 cups cooked chicken, shredded
1 teaspoon dried thyme
1 teaspoon dried parsley
Salt and black pepper to taste
1 cup all-purpose flour
2 teaspoons baking powder
1/2 teaspoon salt
1 cup milk

1. In a large pot, melt the butter over medium heat. Add the onion, garlic, celery, and carrots, and sauté until the vegetables are softened, about 5 minutes.

2. Pour in the chicken broth and bring the mixture to a boil. Reduce the heat to a simmer and add the cooked chicken, thyme, parsley, salt, and pepper.

3. In a separate bowl, mix together the flour, baking powder, and salt. Stir in the milk until a soft dough forms.

4. Drop tablespoonfuls of the dough into the simmering soup. Cover and let simmer for 15 minutes or until the dumplings are cooked through.
