In a shallow bowl, whisk together the buttermilk, half of the garlic powder, half of the onion powder, and a pinch of salt and pepper.
Place the chicken breast in the buttermilk mixture and let it marinate for at least 15 minutes.
In another shallow dish, combine 2 tablespoons of the whole wheat flour with the remaining garlic powder, onion powder, paprika, and salt and pepper.
Remove the chicken from the buttermilk, allowing excess to drip off, then dredge thoroughly in the seasoned flour mixture.
Heat the avocado oil in a medium skillet over medium heat. Once hot, add the chicken and cook for 5-6 minutes per side until golden brown and the internal temperature reaches 165°F. Remove chicken and set aside.
While the chicken cooks, steam the green beans in a small amount of water until tender-crisp, about 5 minutes.
In the same skillet used for the chicken, melt the ghee. Whisk in the remaining 1 tablespoon of flour and cook for 1 minute to create a roux.
Slowly whisk in the almond milk, scraping up any browned bits from the bottom of the pan. Simmer until the gravy thickens, then season with salt and pepper.
Slice the chicken and serve topped with the warm gravy alongside the steamed green beans.
