Preheat oven to 400 degrees F and line a baking sheet with parchment paper.
In a large mixing bowl, combine the turkey meat, olive oil, egg, garlic, onion powder, Italian seasoning, parmesan cheese, parsley, zucchini, salt and pepper. With your hand, mix all of the ingredients together until well combined. The mixture will be very moist but still hold its shape once rolled into balls.
To form the balls, I use a mini ice cream scoop that is equivalent to about 2 tablespoons, and roll the scooped mixture with your hands to form balls. Place on the prepared baking sheet and repeat until you form 24 meatballs.
Bake the meatballs for about 20-25 minutes until browned and evenly cooked through. The meatballs will be firm. Place the meatballs in your favorite marinara sauce in a saucepan and let absorb for a few minutes. Serve on top of your favorite pasta, zoodles, spaghetti squash, or enjoy them just as they are!
