If your chicken breast got overcooked, there isn’t anything you can do to make it more tender or moist. However, that doesn’t mean you have to throw it away, especially with grocery prices so crazy high right now.  Instead of throwing it away, try these two steps to use the overcooked chicken. First, chop up the chicken breast until it is very small. You can do this with a sharp chef’s knife or by pulsing it in a food processor. You will do this because overcooked chicken is tough. Chopping it small will allow much of that toughness to not be as noticeable. Second, use the chicken in a recipe that is naturally moist, like a soup or enchiladas. Since your overcooked chicken is dry, adding moisture with a sauce or broth will help hide that unwanted characteristic.
