Create your dredging station. Add GF flour, salt, and pepper to a medium bowl and whisk, set aside. In another bowl, pour in aquafaba, whisk with fork, set aside. In a 3rd bowl, pour in GF bread crumbs.
Carefully slice each avocado into 3-4 slices. Take one slice, dip in flour mixture, then dip in aqufaba. Let excess drip off before dipping in GF bread crumbs. Place breaded slices either directly into air-fryer or on a piece of parchment paper. Repeat the process until all slices are coated.
Place slices in air-fryer if not already then drizzle olive oil. Carefully rub olive oil into each slice so they get crispy when cooking. Cook at 400F for 3 minutes, take out, flip slices, then cook for another 3 minutes. Let slices cool while you make the dressing.
To make the sauce, whisk all ingredients together into a mixing bowl. Adjust where needed. Set aside.
To assemble the tacos, warm tortillas over open flame then place on serving plate. Add a handful of shredded cabbage to each taco first, then place fried avocado slices and drizzle over sauce. Top with chopped cilantro and serve lime slices
