Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper.
In a large mixing bowl, combine the ground turkey, egg, almond flour, sea salt, black pepper, garlic powder, and dried oregano using your hands until just incorporated.
Gently roll the mixture into 1-inch meatballs and place them on the prepared baking sheet, ensuring they do not touch.
Bake the meatballs for 15 to 18 minutes until they are golden brown on the outside and cooked through to an internal temperature of 165°F.
While the meatballs bake, heat the olive oil in a large skillet over medium heat and sauté the zucchini noodles for 2 to 3 minutes until they are slightly softened but still have a bite.
In a small saucepan, warm the marinara sauce over low heat until it begins to simmer.
Carefully toss the cooked meatballs into the warm marinara sauce to coat them thoroughly.
Divide the zucchini noodles between plates, top with the saucy meatballs, and garnish with freshly chopped parsley.
