Preheat avocado oil in a large cast iron skillet over medium heat.
Combine remaining ingredients in a large mixing bowl and stir until well-combined.
Form 6 large patties.
Place patties in pre-heated avocado oil and fry for 4-6 minutes on one side, before flipping and frying another 3 or 4 minutes on the second side. Cook patties to your preferred done-ness before moving to a plate to cool before serving.
Serve with special sauce and wrap in lettuce, if desired.
