Preheat oven to 425°F. Mix spices and salt in a small bowl. Set aside.
Mix potatoes, carrots, olive oil, garlic and 2 tsp. of the spice mixture in a large bowl, tossing to coat. Arrange vegetables in single layer on large foil-lined shallow baking pan.
Rub chicken with remaining spice mixture. Place on top of vegetables. Roast 40 to 45 minutes or until chicken is cooked through. Stir vegetables before serving.
