1. Make 1 (1/2-inch-deep) cut in each chicken piece; sprinkle evenly with 1/4 teaspoon salt and 1/4 teaspoon pepper. Heat a large Dutch oven over high heat. Add oil to pan; swirl to coat. Place flour in a shallow dish. Dredge chicken in flour. Add chicken to pan; cook 5 minutes on each side. Remove chicken from pan.
2. Add shallots, garlic, and rosemary to pan; cook 2 minutes or until tender, stirring frequently. Add wine to pan; bring to a boil. Cook 1 minute, scraping pan to loosen browned bits. Add remaining 1/4 teaspoon salt, remaining 1/4 teaspoon pepper, chicken stock, sugar, tomatoes, and bay leaf. Bring to a boil; return chicken to pan. Reduce heat to medium; cook, partially covered, 15 minutes or until chicken is done, turning once. Sprinkle with chopped parsley.
