Preheat the oven to 400 degrees.
Heat the olive oil in an OVEN PROOF pan over medium high heat. Season both sides of the chicken hindquarters with sea salt, freshly cracked pepper, and garlic powder, to taste.
Place into the HOT pan and cook, until golden brown, about 3 minutes. Flip the chicken over and place into the oven for 30 minutes. After 30 minutes, slather both sides of the chicken with teriyaki sauce then place back into the oven for 5 minutes, or until chicken is cooked through. Remove from the oven and let the meat rest for 5 minutes prior to cutting. Serve with extra teriyaki on the side if desired.
