Whisk all the ingredients above in a bowl thoroughly. Cut about 6 to 7 semi-frozen chicken breasts in half length-wise. (Semi-frozen breasts are easier to cut, and whole breasts are too thick to grill evenly.) Place chicken breasts and marinade in a 13 x 9 glass baking dish and cover with foil. Or, put both in equal proportions into 1 quart zip-closed bags. Place flat in the refrigerator and allow to sit for at least 6 to 8 hours, but over night is even better, flipping the chicken over periodically. To cook: Preheat oven to 350° F. Place baking dish with chicken, covered, in oven and bake for 45 minutes or until the meat is no longer pink inside. You won't believe how tender and juicy the chicken is! (Discard the marinade.) Or, fire up the grill and cook the chicken over medium heat for about 4-6 minutes per side (depending on how high your heat is). Either serve immediately with your favorite side dish, or as I like to do, allow them to cool and then place in freezer-safe bags and store until you need them! I love using this chicken for pastas, home-made pizzas, grilled sandwiches, you name it!
