Combine all ingredients in a large bowl (except sauce). Mix with your hands until mixture is combined evenly.

Heat a large skillet over medium heat. Drizzle the pan with olive oil.

Using a cookie scoop or ice cream scoop, portion out the meatballs to desired size. Working in batches, add them to the heated pan, and brown on all sides.

When the meatballs are browned, add them to a a large saucepot. When all the meatballs are in the pot, pour over the sauce. Turn the heat to medium/medium low and cook until the meatballs are cooked through (time will vary depending on the size of the meatballs; mine were about 1 1/2" and were done in about 25 minutes).
