Add the garlic, and let everything brown and caramelize for 3 or 4 minutes. Return all of the chicken and sausage to the skillet. Saute in mushrooms for 3 minutes. Pour the white wine and chicken stock to the pan, bring to a boil, and cook until syrupy, about 2 to 3 minutes. Add salt and pepper to taste. Reduce heat to low, and sprinkle with the fresh thyme. Cover the skillet, and cook until the chicken and sausage are glazed and the chicken is tender about 20 to 25 minutes.
