Place the chicken breast in a shallow bowl and pour the buttermilk over it, letting it marinate for at least 15 minutes.
In a separate plate, whisk together the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Remove the chicken from the buttermilk and dredge it through the almond flour mixture until evenly coated.
Heat the avocado oil in a large skillet over medium-high heat.
Place the chicken in the skillet and cook for 5-7 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
While the chicken cooks, steam the green beans until they are tender-crisp.
In a small ramekin, whisk the Dijon mustard and raw honey together to create the glaze.
Serve the chicken immediately with the honey-mustard drizzled over the top and the green beans on the side.
