Pat the chicken dry, season it with pepper, and place it in the hot oil. 3. When the chicken is browned, turn it over and brown the other side. 4. Set the chicken aside. 5. Very carefully, as it is very hot, pour out all but 2 tablespoons of the oil. 6. Add the celery and the garlic.. 7. Over medium-high heat, lightly brown the garlic. 8. Add the wine, chicken stock, vinegar, olives, and thyme. 9. Raise the heat to high and bring to a boil. Reduce the liquid for 2 to 3 minutes. 10. Add the chicken back. 11.

Plate the chicken, drizzle with the sauce, and serve, garnished with thyme.
