1Heat a cast iron skillet, or other oven safe pan, over medium heat with your avocado oil. Just let the oil heat up for a few minutes.
2Preheat your oven to 350 degrees fahrenheit.
3Once your skillet is hot, add your chicken and sprinkle generously with salt and pepper. Let the chicken cook for a bit (about 7-8 minutes until the bottom sides brown a little). The chicken will stick a little to your pan. I just use tongs to poke things around and detach the chicken from the pan as needed.
4Once the bottoms are browned, flip your chicken over and sprinkle the new topside with more salt and pepper. Then, add the oregano, squeeze a little lemon juice over the chicken and top with your lemon slices.
5Use hot pads to remove your skillet from the oven and carefully transfer it to the oven. Cook for 12-15 more minutes until the chicken is done.
