Carefully slice the tops off each bell pepper and remove the seeds and membranes, ensuring they are hollowed out. Arrange the peppers cut-side up in a baking dish, ready to be filled.
In a large skillet, pour in a drizzle of olive oil and heat over medium heat. Add the ground chicken and sauté, breaking it up with a spatula, for about 5-7 minutes or until it's fully cooked and lightly browned.
Once the chicken is cooked, stir in the marinara sauce, cooked quinoa, Italian seasoning, garlic powder, along with a pinch of salt and pepper. Mix well until all ingredients are thoroughly combined, then remove the skillet from the heat.
Incorporate half of the shredded mozzarella cheese and half of the grated Parmesan cheese into the chicken mixture, stirring until the cheeses are melted and evenly distributed throughout the filling.
Take the chicken mixture and spoon it generously into each prepared bell pepper, ensuring they are filled to the top. Sprinkle the remaining mozzarella and Parmesan cheeses evenly over the stuffed peppers.
For added flavor and moisture during baking, pour a little extra marinara sauce around the base of the peppers in the dish.
To lock in the moisture, cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 25 minutes.
After 25 minutes, carefully remove the foil to allow the cheese to become golden and bubbly. Continue baking for an additional 10-15 minutes, watching closely for that perfect golden brown topping.
Once done, remove the dish from the oven and let the stuffed peppers cool slightly for about 5 minutes. Garnish with fresh basil leaves just before serving for a touch of color and flavor.
