Line a baking sheet with foil and spray/drizzle oil to prevent the turkey meatballs from sticking. Preheat the oven to 400°F.
In a large bowl, mix together all of the ingredients until everything is incorporated. Optional but highly encouraged, do this while using gloves to make clean up easier.
Using a cookie/ice cream scoop, scoop out meatballs and place onto the lined baking sheet. While you don't need to use a cookie scooper, this will help make the meatballs all one shape and help them bake evenly.
Bake the turkey meatballs for 15 minutes on the middle rack, making sure to turn the pan halfway through cooking.
For a little bit more color and crispness on the meatballs, broil for 4-5 minutes on the middle rack. Make sure to keep an eye on the meatballs so they don't burn.
Notes
Forming the turkey meatballs. Use a cookie/ice cream scoop to make sure each meatball is the same size and, in turn, cooked at the same time as the rest of the meatballs.
Storing. Once the meatballs come out of the oven, make sure to cool completely before storing in an airtight container in the fridge for up to a week.
Reheating. Pop a few meatballs in the microwave, covered with a damp paper towel to keep in the moisture, for about 1-2 minutes.
