In a large mixing bowl, whisk together dill pickle juice, brown sugar, salt, pepper and red pepper flakes.
Use tongs to place the chicken breasts in the bowl with the marinade.
Cover and refrigerate for 4 hours or overnight.
Preheat the grill to 350 degrees F. Gently brush the grates of the grill with the oil to prevent the chicken from sticking.
Place the chicken breasts on the grill. Cook for 5-7 minutes per side until the chicken reaches an internal temperature of 165 degrees F.
Remove the chicken from the grill, let the chicken rest for 5 minutes. Then it’s ready to slice and enjoy.

Notes
Refrigerate the leftovers in an airtight container for up to 5 days. We use an instant-read meat thermometer to make sure that the chicken is cooked to a safe temperature before eating.
