Preheat your oven to 400°F.
In a mixing bowl, combine the lean ground turkey, egg white, whole wheat breadcrumbs, minced garlic, and chopped fresh basil. Mix until evenly combined.
Form the mixture into small meatballs, about the size of a golf ball.
Place the meatballs on a lightly greased baking sheet and bake for 15-18 minutes, or until cooked through.
While the meatballs bake, use a spiralizer or vegetable peeler to create zucchini noodles from the medium zucchini.
In a skillet, heat olive oil over medium heat. Add the zucchini noodles and sauté briefly until just tender, about 2-3 minutes.
Warm the tomato sauce in a small pot or in the microwave, then gently toss with the zucchini noodles.
Plate the zucchini noodles, top with the turkey meatballs, and drizzle any remaining sauce over the top.
Garnish with extra basil if desired and serve warm.
