An hour before cooking, brine the chicken in pickle juice.
Preheat the oven to 400F. Remove chicken from brine, toss to coat in salt, pepper and garlic powder.
In an oven safe grill pan heat the vegetable oil and add the chicken thighs; cook for two minutes per side, and then place in the preheated oven. Cook for 15 minutes, or until the chicken is no longer pink and become opaque.
