Place the chicken breast in a shallow dish and pour the buttermilk over it, ensuring it is fully coated, and let it marinate for 15 minutes.
In a separate small bowl, whisk together the whole wheat flour, garlic powder, onion powder, paprika, sea salt, and black pepper.
Remove the chicken from the buttermilk, allowing any excess to drip off, then dredge it thoroughly in the seasoned flour mixture until evenly coated.
Heat the avocado oil in a cast-iron skillet over medium-high heat until shimmering.
Carefully place the chicken in the hot skillet and cook for 5-6 minutes per side until the crust is deep golden brown and the internal temperature reaches 165°F.
While the chicken is cooking, steam the green beans in a steamer basket over boiling water for 4-5 minutes until tender-crisp.
Remove the chicken from the pan and immediately drizzle the raw honey over the hot surface so it melts into a glossy glaze.
Serve the honey-glazed chicken immediately alongside the fresh steamed green beans.
