In a large bowl, combine all of the meatball ingredients. Using your hands, mix together until just combined. Form into meatballs about the size of a golf ball and place on a sheet pan. Refrigerate 1-4 hours prior to cooking.
Heat 2 tablespoons of avocado oil and place the pan over medium-high heat. Add the meatballs and cook until browned, around 5 minutes. Flip and cook until the other sides are browned. Place in oven preheated oven @ 350 for 12 minutes.
Transfer to a serving platter along with the fried potatoes (if making), stir fried veggies, taziki sauce and greek salad for a wonderful meal!
