Make the meatballs in a medium bowl. Combine the ingredients. Use your hands to mix until the ingredients are evenly distributed. Wet your hands with cold water and shape the meat into balls. Cover with plastic wrap and refrigerate at least 45 minutes or until very cold.
Make the sauce in a small bowl by whisking the ingredients together.
Spray grill with Pam before placing over hot coals. Dip each meatball in olive oil before placing on the grill. Grill over direct heat until the meat is thoroughly cooked but not dry, 6-8 minutes, gently turning occasionally. Arrange on a platter with toothpicks. Serve with sauce.
