Microwave butternut squash spirals as per instructions on the bag; drain all excess water and set aside to dry.

In a broiler-safe pan sprayed with nonstick cooking spray, add ground turkey. Cook on medium heat for about 5 minutes, or until turkey is no longer pink. Break up clumps into smaller pieces as you go.

Add the onions, peppers, and taco seasoning to the pan. Cook until vegetables are soft, about 5-7 minutes.

Add the garlic, spinach, and 1/4 cup of the marinara sauce to the pan. Stir until the spinach has wilted and the sauce is mixed in. Then add butternut squash and mix in.

Gently pat down ground turkey and squash mixture and pour the remaining marinara sauce on top. Spread out across the pan evenly.

In a separate bowl, whisk the egg. Mix in the ricotta cheese, parmesan, salt, pepper and garlic powder. Layer ricotta cheese mixture on top of the sauce.

Finally, top with mozzarella cheese. Place in the oven on broil for 5-10 minutes or until the cheese starts to brown. Take out, top with fresh basil, fresh ground pepper, and grated parmesan cheese, if desired! The grated parmesan is optional but highly recommended!
