Place the chicken breast between two pieces of parchment paper and pound to an even thickness to ensure uniform cooking.
Submerge the chicken in a bowl with the buttermilk and let marinate for at least 15 minutes to tenderize the meat.
In a shallow dish, whisk together 2 tablespoons of flour, garlic powder, onion powder, sea salt, and black pepper.
Remove chicken from buttermilk, letting excess drip off, then dredge thoroughly in the seasoned flour mixture until fully coated.
Heat avocado oil in a skillet over medium heat and cook the chicken for 5-6 minutes per side until golden brown and cooked through.
Remove chicken from the pan and set aside; wipe out excess oil but keep the flavorful browned bits in the pan.
Melt ghee in the same skillet, whisk in 1 teaspoon of flour for 1 minute, then slowly pour in almond milk while whisking until thickened into a gravy.
Steam the green beans until tender-crisp and serve alongside the chicken drizzled with the warm creamy gravy.
