Preheat your oven to 375°F and line a small baking sheet with parchment paper.
In a small mixing bowl, combine 3 tbsp almond flour, Greek yogurt, baking powder, and 0.125 tsp sea salt to form a thick dough.
Shape the dough into a round biscuit and place it on the baking sheet; bake for 12-15 minutes until the top is lightly browned.
While the biscuit bakes, slice the chicken breast into thick strips and place them in a bowl with the buttermilk to marinate for 10 minutes.
In a shallow dish, whisk together 1 tbsp almond flour, arrowroot starch, garlic powder, onion powder, 0.25 tsp sea salt, and black pepper.
Remove chicken from the buttermilk and dredge each piece in the flour mixture, pressing firmly so the coating adheres.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and cook for 4-5 minutes per side until the exterior is crispy and the internal temperature reaches 165°F.
Serve the hot fried chicken immediately alongside the fresh almond flour biscuit.
