Slice the chicken breast into even strips to ensure uniform cooking.
Place the chicken strips in a bowl with the buttermilk and let marinate for at least 20 minutes in the refrigerator.
In a shallow dish, whisk together the almond flour, arrowroot starch, garlic powder, onion powder, sea salt, black pepper, and paprika.
Remove each chicken strip from the buttermilk, allowing the excess to drip off, and dredge thoroughly in the seasoned flour mixture.
Heat the avocado oil in a large non-stick skillet over medium-high heat until shimmering.
Carefully place the chicken in the skillet and fry for 4-5 minutes per side until the exterior is golden-brown and crispy.
While the chicken is cooking, steam the green beans in a small amount of water until they are tender-crisp and bright green.
Serve the hot crispy chicken immediately alongside the steamed green beans.
