Preheat your oven to 400°F.
In a bowl, combine the lean ground turkey, egg, minced garlic, chopped fresh parsley, salt, and pepper. Mix until just blended.
Form the mixture into small meatballs, about 12-15 pieces.
Place the meatballs on a parchment-lined baking sheet and bake for 15-18 minutes, until cooked through.
While the meatballs bake, use a spiralizer or vegetable peeler to create zucchini noodles from the zucchinis.
Lightly sauté the zucchini noodles in a non-stick pan over medium heat for 2-3 minutes, just until slightly tender.
Warm the tomato sauce in a small saucepan, seasoning with a pinch of salt and pepper.
Plate the zucchini noodles, top with the baked turkey meatballs, spoon over the tomato sauce, and finish with a sprinkle of Parmesan cheese and a drizzle of olive oil.
Serve immediately and enjoy your balanced, lean meal!
