Place chicken between 2 sheets of heavy-duty plastic wrap, and flatten to 1/4-inch thickness, using a meat mallet or rolling pin.
Combine lime juice and oil; brush over both sides of chicken. Rub both sides of chicken with jerk seasoning.
Place chicken on grill rack coated with cooking spray; grill, covered, 5 to 6 minutes on each side or until done.
Tip: Jerk seasoning is a Jamaican seasoning blend often used on grilled meats. The blend is generally a combination of chiles, thyme, cinnamon, allspice, garlic, and onions. Look for jerk seasoning in the spice section of the supermarket.
