Greek-Style Lemon Roast Chicken

3-4 lbs. frozen chicken breasts
salt and black pepper
1 medium lemon, washed, zested, halved and squeezed
1 medium lemon, sliced
½ cup Greek vinaigrette dressing
2 cloves garlic, crushed
½ cup Feta cheese, crumbled

Mix lemon zest, juice, dressing and garlic; toss with frozen chicken breasts in a large sealable plastic bag. Marinate overnight, or 4-6 hours, in the refrigerator. Preheat oven to 350°F. Place contents of plastic bag in a 13x9-inch baking dish.
Place lemon slices over chicken breasts. Bake 1½ hours or until chicken is cooked through (reaches an internal temperature of 180°F), basting occasionally. Sprinkle with crumbled Feta cheese before serving.
