Preheat the oven to 400°F.
In a bowl, combine the lean ground turkey, egg whites, rolled oats, minced garlic, chopped fresh parsley, and salt & pepper.
Mix the ingredients until just combined; avoid overmixing to keep the meatballs tender.
Form the mixture into small meatballs, about the size of a golf ball.
Heat olive oil in an oven-safe skillet over medium heat. Brown the meatballs on all sides for about 5 minutes.
Transfer the skillet to the preheated oven and bake for an additional 10-12 minutes until the meatballs are cooked through.
While the meatballs are baking, spiralize the zucchini into noodles using a spiralizer, or slice into thin strips.
Lightly sauté the zucchini noodles in a separate pan over medium heat for 2-3 minutes until just tender. Season lightly with salt and pepper.
Serve the turkey meatballs over the zucchini noodles, garnished with additional parsley if desired.
