Add the ground chicken, apple cider vinegar, spices, almond flour, and barbecue sauce to a large mixing bowl. Use your hands to mix all of the ingredients together until well combined.
Next, use a cookie scoop or tablespoon measuring spoon to scoop the ground chicken mixture. Then, use your hands to roll the mixture into meatballs. Place the meatballs on a sheet pan lined with parchment paper.
Drizzle a tablespoon of avocado or olive oil over the meatballs. Bake the meatballs at 425 degrees for 15-20 minutes until fully cooked through.
When the meatballs are fully cooked, transfer them to a large mixing bowl. Drizzle more barbecue sauce over the meatballs and then toss them until well coated in the sauce.
Once the meatballs are sauced to your liking, transfer them a serving dish. Serve with extra barbecue sauce for dipping and enjoy!
