For the Chicken, mix orange juice, oil and 1 teaspoon of the thyme in small bowl. Place chicken in large resealable plastic bag or glass dish. Add marinade; turn to coat well. Refrigerate 30 minutes or longer for extra flavor. For the Relish, mix all ingredients in medium bowl. Cover. Refrigerate until ready to serve.
Preheat oven to 400°F. Mix brown sugar, paprika, remaining 1/2 teaspoon thyme and salt in small bowl. Remove chicken from marinade. Discard any remaining marinade. Rub chicken evenly with paprika mixture. Place chicken on foil-lined baking pan.
Bake 15 to 17 minutes or until chicken is cooked through. Or, grill chicken over medium-high heat 6 to 8 minutes per side or until cooked through. Serve chicken with Orange Relish.
