Preheat the oven to 400°F.
In a mixing bowl, combine the lean ground turkey, egg white, almond flour, garlic powder, onion powder, salt, and pepper. Mix thoroughly until all ingredients are evenly incorporated.
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 lightly drizzle or spray with olive oil.
Bake the meatballs in the preheated oven for 15-18 minutes or until fully cooked through, turning halfway for even baking.
While the meatballs are baking, spiralize the zucchini to create noodles. If desired, lightly sauté the zucchini noodles in a non-stick pan for 2-3 minutes to slightly soften them, keeping a crisp texture.
Warm the tomato sauce in a small saucepan over low heat.
Plate the zucchini noodles, top with the baked turkey meatballs, and drizzle the warm tomato sauce over the top.
Serve immediately and enjoy your balanced, flavorful meal.
