In a large bowl, combine the ground turkey, egg, almond flour, sea salt, black pepper, garlic powder, and dried oregano until well incorporated.
Form the mixture into 1-inch meatballs, ensuring they are uniform in size for even cooking.
Heat half of the olive oil in a large skillet over medium-high heat and sear the meatballs until they are golden brown on all sides.
Pour the marinara sauce into the skillet with the meatballs, reduce the heat to low, cover, and simmer for 10 minutes until the meatballs are cooked through.
While the meatballs simmer, use a spiralizer to create noodles from the zucchini and pat them dry with a paper towel to remove excess moisture.
In a separate skillet, heat the remaining olive oil over medium heat and quickly sauté the zucchini noodles for 2-3 minutes until they are tender-crisp.
Divide the zucchini noodles between plates, top with the meatballs and marinara sauce, and garnish with freshly torn basil leaves.
