Slice the chicken breast into thick strips and place them in a bowl with the buttermilk to soak for 20 minutes.
In a shallow dish, whisk together the 2 tablespoons of whole wheat flour, almond flour, garlic powder, onion powder, sea salt, black pepper, and paprika.
Remove each chicken strip from the buttermilk, letting the excess drip off, and dredge thoroughly in the flour mixture, pressing to ensure a thick coating.
Place the chicken in an air fryer basket sprayed lightly with oil and cook at 375°F for 12 to 15 minutes, flipping halfway through, until the coating is golden and crunchy.
While the chicken cooks, melt the ghee in a small saucepan over medium heat, then whisk in the remaining teaspoon of flour for 1 minute to create a roux.
Slowly pour the almond milk into the saucepan, whisking constantly until the gravy thickens and becomes smooth.
Steam the green beans in a small amount of water until they are bright green and tender-crisp.
Serve the crispy chicken strips drizzled with the warm gravy alongside the steamed green beans.
