In a large bowl, combine ground beef, breadcrumbs, finely diced onion and mashed garlic.
Add in the spices.
In a small bowl, mix baking soda, water and lemon juice. Pour this into the ground beef mixture. Mix well with your hand. Knead it for about a minute so that everything is combined well.
Cover and let it sit in the refrigerator overnight or at least 2 hours.
Roll them into meatballs.
Heat olive oil in a cast iron pan or any non-stick pan. Cook the meatballs over high heat, flipping them over or shaking the pan occasionally so that all sides are cooked for about 3 minutes. Don't overcrowd the pan, cook the meatballs in batches until they finish or save some to freeze.

NOTES
If you can’t find 80% lean beef, use a mixture of lamb and beef (50% lamb, 50% beef). Prep time includes waiting the meatballs in the refrigerator.
