Preheat the oven to 400°F and spray a 9x13 inch baking dish with cooking spray.

In a medium mixing bowl, combine ground turkey, bread crumbs, eggs, diced onion, Italian seasoning, garlic powder, salt, and pepper.

Stir to combine without over mixing.

Using a cookie scoop, portion the meat mixture and place on the prepared baking dish. Repeat until all the mixture is used.

Optionally, roll the meatballs into uniform circles with your hands, using oil residue to prevent sticking.

Bake for 15-20 minutes or until the internal temperature reaches 165°F.

Remove from oven and serve hot.
