Place the chicken breast between two sheets of parchment paper and pound to an even 1/2-inch thickness.
In a shallow bowl, soak the chicken in buttermilk for 15 minutes to tenderize.
In a separate bowl, whisk together the almond flour, arrowroot, garlic powder, onion powder, paprika, salt, and pepper.
Dredge the soaked chicken in the flour mixture, pressing firmly to ensure a thick and even coating.
Heat the avocado oil in a cast-iron skillet over medium-high heat until it begins to shimmer.
Carefully place the chicken in the pan and cook for 4-5 minutes per side until the crust is golden and the internal temperature reaches 165°F.
While the chicken cooks, toss the shredded cabbage with apple cider vinegar and a pinch of salt for a bright, crunchy slaw.
Serve the crispy chicken immediately alongside the fresh slaw for a balanced and satisfying meal.
