In a large mixing bowl, add the ground turkey, quick oats, shredded cheese, onion powder, kosher salt, garlic powder, and Italian seasoning, and then mix until it's evenly combined.
Using a large cookie scoop (1/4 cup or 3 tablespoons), form and roll 15 meatballs. You can place them on the baking sheet to stage them.
Add 1-2 tablespoons of regular olive oil to a large skillet over medium-high heat and add the meatballs. You may need to brown them in batches.
