Mix together well. Use a baller to drop them into a pan with hot bacon grease (or ghee or coconut oil) and brown on all sides. (Or just a spoon will work fine,too.) These are kind of a pain, even with my huge awesome stainless steel electric frying pan, because you have to keep standing there and turning them as each batch cooks. But maaaaaaaan are they good. I love meatballs! Mary Jo then puts them into a 9×13 pan in the oven with a little beef stock and foil over the top so they stay warm. I think I’d do that if I were serving them right away, but I knew that for this recipe they’d be baking in the oven and getting hot again.
***Tiffany in the comments just had a great idea: bake these in the oven so you don't have to stand over them as they cook and it will be easier! I tried it and it IS so much easier! I didn't brown them first either and they were so good!
Notes
***Also, here's a recipe for grain-free meatballs (not even almond flour), in case you need one.
