Heat a large skillet over medium heat. Add a drizzle of Olive Oil and the ground turkey. Using a wooden spoon, start to break up the ground turkey. Add the bell peppers, onion, ½ teaspoon garlic, dash or two of red pepper flakes, salt, pepper, and about 2 teaspoons of the Italian seasoning.
Continue to cook until the turkey is done and the peppers and onions are softened.
Add the rice, diced tomatoes, and ½ the can of tomato sauce to the turkey mixture. Pour the turkey and rice mixture into a 13 x 9 baking dish that has been sprayed with non-stick spray.
Place the skillet back on the burner and add the remaining half can of tomato sauce. Fill the empty tomato sauce can about half full with water and add to the tomato sauce along with a little more salt and pepper, the remaining 1 teaspoon of Italian seasoning, and ½ teaspoon of garlic powder. Warm slightly.
Pour the tomato sauce over the top of the turkey and rice mixture. Sprinkle with cheese. I used a combination of mozzarella and cheddar.
Place the casserole dish in the oven that has been preheated to 375 degrees. Warm the Bell Pepper Casserole until bubbly and the cheese has melted.
Remove from oven and serve.
