Step 1

Spray a large roasting pan with non-stick spray. Add potatoes, carrots, onions, vinegar, oil, garlic, 1 teaspoon thyme, 1 teaspoon rosemary, tarragon, salt, and pepper. Mix well. Roast, uncovered, at 425 degrees for 30 minutes. Stir once, halfway through cooking time. Add green beans and roast for 10 more minutes.

Step 2

Meanwhile, pour wine into a large saucepan. Add remaining 1/2 teaspoon thyme and 1/2 teaspoon rosemary. Bring to a boil. Add chicken pieces and reduce heat to medium-high. Cook, uncovered, until chicken is cooked through, about 12 minutes.

Step 3

Add roasted vegetables to chicken and wine. Stir in 2 1/2 cups of broth. In a small bowl, combine flour with remaining 1/2 cup broth and stir until lump free. Add flour mixture to chicken and vegetables. Cook until stew is bubbly and has thickened, about 3 minutes. Serve hot.
