Prepare the bell peppers by cutting the tops off and removing the seeds and membranes. Place the hollowed peppers upright in a baking dish.
In a large skillet, heat the extra virgin olive oil over medium heat. Add the ground chicken and sauté for about 5-7 minutes until browned and fully cooked.
Season the chicken with garlic powder, onion powder, salt, and freshly ground black pepper. Mix evenly.
Add the chopped spinach and cauliflower rice into the skillet. Stir gently and cook for an additional 3-4 minutes until the spinach has wilted and the cauliflower rice is tender.
Remove the skillet from the heat. Stir in 1/2 cup of shredded mozzarella and the grated Parmesan cheese until melted and fully incorporated.
Carefully stuff each bell pepper with the chicken and spinach mixture, packing the filling tightly.
Top each stuffed pepper with the remaining mozzarella cheese.
Cover the baking dish with aluminum foil and bake for 25 minutes. Remove the foil and continue baking for another 10-15 minutes until the cheese is bubbly and golden brown.
Once baked, remove from the oven and allow to cool slightly for about 5 minutes. Garnish with finely chopped fresh parsley before serving.
