1. In a shallow bowl, combine 1 tablespoon of the flour with generous pinches of salt and pepper. Toss with the chicken.
2. In a large flameproof casserole on medium heat, heat 1 tablespoon of the oil. Brown half the chicken. Remove the chicken from the pan; set aside. Use the remaining 1 tablespoon of oil to brown the remaining chicken and remove it from the pan.
3. Turn the heat to medium-low. Add the butter. Cook the onions, garlic, and celery over medium heat, stirring often, for 5 minutes. Add the remaining 1 tablespoon of flour. Cook, stirring, for 2 minutes.
4. Stir in the wine, stock, and mustard. Scrape the bottom of the pan to remove the sediment.
5. Return the chicken to the pan and bring the mixture to a boil. Lower the heat, cover the pan, and simmer for 5 minutes.
6. Turn off the heat and add the lettuce, grapes, parsley, and tarragon. Cover and let the mixture sit for 5 minutes. Serve with rice. Adapted from "Jamie's Kitchen"
