Preheat your oven to 400°F.
In a bowl, combine the lean ground turkey, egg white, whole wheat breadcrumbs, grated Parmesan, chopped onion, minced garlic, fresh basil, salt, and pepper. Mix until just combined, being careful not to overwork the meat.
Form the mixture into small meatballs, roughly the size of a walnut. Place them on a baking sheet lined with parchment paper.
Bake the meatballs in the preheated oven for 15-18 minutes, or until they are cooked through and lightly browned.
While the meatballs are baking, spiralize the zucchini to create noodles. If a spiralizer is unavailable, use a vegetable peeler to form long ribbons.
In a non-stick pan, warm the olive oil over medium heat and toss the zucchini noodles for 2-3 minutes until slightly tender but still crisp.
Plate the zucchini noodles as a base and top with the cooked turkey meatballs. Optionally, garnish with extra basil or a sprinkle of Parmesan before serving.
