Pre-heat oven to 400 degrees F. Whisk together Greek yogurt, Dijon mustard, lemon juice, olive oil, the garlic and salt and pepper.
Heat a little olive oil over medium heat in a cast iron pan.
When the oil is hot (shimmering in the pan), add the chicken cutlets. Sprinkle with some Kosher salt. Do NOT touch for 3 minutes.
After 3 minutes of NOT touching, flip and cook for another 2 minutes.
Remove pan from heat. Pour some of the Greek yogurt dressing over the chicken cutlets. Place the whole pan into the oven.
Bake in the oven for approximately 5 minutes (set a timer). Cook to internal temperature of 165 degrees F.
Serve with rice, steamed veggies and extra Greek yogurt sauce for dipping.
