Chicken breasts can be a little dry, so some people choose to marinate or brine them before cooking. This will help keep the chicken moist and flavorful. If you’d like to do this, simply combine 1/2 cup of water with 1/4 cup of vinegar and 1 tablespoon of salt in a large Ziploc bag. Add the chicken breasts to the bag, seal it and let it sit for at least 30 minutes. This step is however not necessary and tastes great without it!
