Preparation

1. In a small bowl, whisk together the lemon zest, lemon juice, paprika, oregano, garlic, salt, pepper and olive oil. Place chicken in a plastic zip lock bag and pour marinade over chicken breasts. Place sealed bag in refrigerator and allow chicken to marinade for 30 minutes to 1 hour.
2. Place chicken breast halves on cutting board and cut each breast into two pieces horizontally. Place the halves onto a piece of plastic wrap and then cover with another piece of wrap. Pound the pieces of chicken to about 1/4-inch thickness using a meat mallet or the bottom of a small skillet. Place chicken in a plastic zip lock bag or a shallow baking dish and pour marinade over chicken breasts. Place sealed bag or dish in refrigerator and allow chicken to marinade for 30 minutes to 2 hours.
3. Warm grill or grill pan over medium-high heat. Remove chicken breast from marinade and cook 4-8 minutes on each side or until internal temperature reaches 165F.
