Place the chicken breast in a shallow bowl and pour the buttermilk over it, ensuring it is fully coated; let it marinate for at least 15 minutes.
In a separate shallow dish, whisk together the almond flour, arrowroot starch, smoked paprika, garlic powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, allowing excess to drip off, and dredge it thoroughly in the flour mixture, pressing the coating onto the meat.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 5-6 minutes per side, or until the crust is golden brown and the internal temperature reaches 165°F.
While the chicken cooks, steam the green beans in a small amount of water until tender-crisp.
In a small microwave-safe bowl, combine the raw honey and cayenne pepper; warm for 10 seconds until pourable.
Serve the crispy chicken alongside the steamed green beans and drizzle the spicy honey over the chicken immediately.
