Combine meat, salt, almond meal and onion powder (if using) in a medium bowl. Using clean hands and a soup spoon, scoop a spoon sized chunk and roll into a ball with your hands. Place in a baking dish large enough to hold the meatballs in a single layer (I line mine with baking paper so it looks prettier in the picture and is easier to clean up). Repeat with remaining mixture.
Pop the balls in the oven for 10-15 minutes or until browned on top and no longer pink in the middle.
