Add chicken breast and chipotles in adobo to a resealable container and massage until the chicken is coated in the sauce. Marinate for at least one hour, but preferably overnight.
Add corn, red onion, bell pepper, jalapeno, and garlic to a bowl. Set aside.
Bring water almost to a boil, then add sugar and salt and stir until dissolved. Add apple cider vinegar, Flavor God Garlic Lovers Seasoning, and black pepper and stir.
Pour pickling liquid over corn mixture and mix, then push the corn mixture under the liquid as much as possible. Cover and marinate for at least 1 hour.
Before serving corn relish, drain most of the pickling liquid out and stir in cilantro.
Grill chicken, slice, and serve with corn relish and other sides, as desired.
