Pat the chicken dry well with paper towels. Drizzle with a little olive oil and season it all over with the sea salt, black pepper, garlic and onion powders and smoked paprika.
Meanwhile heat a large cast iron pot over medium high flame. Add a lug of oil, just enough to coat the bottom in a very thing layer and pan sear the andouille sausage slices on both sides until golden.
Sear the chicken in the drippings from the andouille sausage until nice and golden on both sides. Approximately 3 minutes per side, taking good care not to burn the spices.
