Preheat your oven to 400°F.
In a bowl, combine lean ground turkey, egg, almond flour, chopped parsley, minced garlic, salt, and pepper. Mix until just combined.
Form the mixture into small meatballs, about the size of a golf ball.
Place the meatballs on a baking sheet lined with parchment paper and bake for 15-18 minutes, or until cooked through.
While the meatballs are baking, spiralize the zucchini into noodles.
Heat the olive oil in a pan over medium heat, add the zucchini noodles and sauté for 2-3 minutes until just tender, avoiding overcooking.
Warm the marinara sauce in a small pot.
Plate the zucchini noodles, top with turkey meatballs, and drizzle with marinara sauce.
Garnish with additional fresh parsley if desired and serve immediately.
