01 - In a large bowl, gently mix ground turkey, egg, gluten-free breadcrumbs or almond flour, Parmesan cheese, minced garlic, parsley, oregano, salt, and black pepper until just combined. Shape into sixteen even meatballs.
02 - Heat two tablespoons of olive oil in a large skillet over medium heat. Brown the meatballs on all sides for about five to seven minutes, working in batches if needed. Transfer browned meatballs to a plate.
03 - In the same skillet, warm one tablespoon of olive oil. Sauté the chopped onion until soft, approximately three minutes. Add minced garlic and cook for one minute. Stir in crushed tomatoes, dried basil, oregano, salt, pepper, and optional sugar, then bring to a simmer.
04 - Return the browned meatballs to the skillet nestling them into the marinara. Cover and simmer on low heat for fifteen to twenty minutes, ensuring meatballs are cooked through.
05 - While the sauce simmers, heat one tablespoon of olive oil in a large skillet over medium-high heat. Add spiralized zucchini, season with salt and pepper, and sauté for two to three minutes until tender but still firm. Drain any excess moisture.
06 - Divide the zucchini noodles among plates. Top with turkey meatballs and spoon over marinara sauce. Garnish with fresh basil and additional Parmesan if desired.
