Preheat your oven to 400°F.
In a bowl, combine the lean ground turkey with the egg white, a finely minced garlic clove, a pinch of salt, and pepper. Mix gently until just combined to form the meatball mixture.
Form the mixture into small meatballs, about 1 to 1.5 inches in diameter, and place them on a baking sheet lined with parchment paper.
Bake the meatballs in the preheated oven for about 15-18 minutes or until cooked through.
While the meatballs are baking, prepare the fresh marinara. Chop the fresh tomatoes into small pieces and place them in a saucepan along with a drizzle of olive oil. Simmer over medium heat, stirring occasionally, until the tomatoes break down into a chunky sauce, about 8-10 minutes. Season with salt, pepper, and add fresh basil.
Using a spiralizer or a vegetable peeler, create zucchini noodles from the medium zucchini.
To serve, place the zucchini noodles in a bowl, top with the warm, fresh marinara sauce, and gently nestle the turkey meatballs on top.
Finish with an extra sprinkle of fresh basil. Enjoy your healthy, balanced meal!
