Preheat your oven to 400°F and line a small baking sheet with parchment paper.
In a small mixing bowl, combine 0.25 cup cassava flour, Greek yogurt, baking powder, and honey to form a soft dough.
Shape the dough into a thick round biscuit and place it on the baking sheet; bake for 12-15 minutes until the top is golden and firm.
While the biscuit bakes, slice the chicken breast into even strips and place them in a shallow bowl with the buttermilk to marinate.
In a separate shallow dish, whisk together 2 tbsp cassava flour, garlic powder, onion powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, allowing the excess to drip off, and dredge thoroughly in the seasoned flour mixture.
Heat the avocado oil in a non-stick skillet over medium-high heat.
Add the chicken to the skillet and pan-fry for 4-5 minutes per side until the crust is golden-brown and the chicken is cooked through.
Remove the biscuit from the oven and serve immediately alongside the hot, crispy chicken strips.
