You can double or triple the recipe and make a lot of veggie-loaded meatballs at once. Then, simply cook from frozen for healthy, delicious, and homemade meatballs!
In a large skillet, heat avocado oil on medium heat. Then add the onion and celery. Sauté for 4-5 minutes. Add the garlic for 1 minute to cook and remove from heat.
In a large bowl combine the beef, egg, onion mixture, oat flour, Worcestershire sauce, sea salt, pepper, and allspice. Mix well and form meatballs with your hands
To freeze meatballs, place them on the parchment-lined baking sheet, making sure that they do not touch. Freeze the meatballs, and once fully frozen, transfer them into a labeled freezer bag.
Frozen meatballs go great from the freezer into a crockpot.
Top with spaghetti sauce, barbecue sauce, or your favorite sauce and cook on low for 5-6 hours in the slow cooker.
