Preheat your oven to 375°F (190°C) and lightly grease a small baking dish with the olive oil.
Roughly chop the fresh spinach and the artichoke hearts into bite-sized pieces.
In a medium mixing bowl, combine the Greek yogurt, parmesan cheese, garlic powder, sea salt, and black pepper until smooth.
Fold the chopped spinach and artichoke hearts into the yogurt mixture until well incorporated.
Place the cauliflower rice at the bottom of the baking dish as a base, then lay the chicken breast on top.
Spread the spinach artichoke mixture evenly over the chicken, ensuring it is fully covered.
Bake for 25 to 30 minutes, or until the chicken reaches an internal temperature of 165°F and the topping is slightly golden and bubbly.
Let the dish rest for 5 minutes before serving to allow the juices to redistribute.
