Try this first.
take the chicken whole breast and put them in a storing container cover with fresh squeezed lemon juice. Just squeeze the lemons right over the chicken enough to cover them all real good. Then cover the chicken with a good amount of rosemary,sea salt, and pepper. Place chicken in fridge over night. Cook as you always do the next day.
You can eat them just like this or pre chop the chicken into bite size peaces to put on salads.
