In a large bowl, combine all the ingredients (except for the avocado oil). Using a fork, mix until well combined.
Using your hands, scoop about 2 tbsp of the mixture at a time and form it into a croquette (an oval shape, almost like an egg). Set aside on a clean plate until all are formed.
In a skillet over medium heat, heat the avocado oil until hot but not yet smoking. When hot, gently lay the croquettes in a single layer and fry until a deep golden crust forms on all sides, about 2-3 minutes per side.
Transfer cooked croquettes to a paper towel lined plate to remove excess oil. Serve alone or with desired dipping sauce. I serve mine with Whole30 Tartar Sauce.
