Preheat the oven on 350 degrees Fahrenheit. Spray a baking sheet with cooking spray and set aside. Optionally, pour some oil in a frying pan and heat over medium heat.
Place all the ingredients except oil in a large bowl and combine thoroughly with your hands. Form into golf ball sized meatballs.
To bake the meatballs, place them in rows on the baking sheet, with space in between. Bake for 20-25 minutes, or until the internal temperature reaches 165 degrees.
To fry, place the meatballs in the heated pan and fry evenly on all sides, approximately 8-10 minutes, or until the internal temperature reaches 165 degrees.
