Slice the chicken breast into even strips and submerge them in the buttermilk for at least 20 minutes to tenderize.
In a shallow bowl, whisk together the almond flour, arrowroot powder, smoked paprika, garlic powder, sea salt, and black pepper.
Remove each chicken strip from the buttermilk, allowing the excess to drip off, and dredge thoroughly in the flour mixture until well-coated.
Heat the avocado oil in a large skillet over medium-high heat until the oil is shimmering.
Carefully place the chicken in the pan and cook for 4-5 minutes per side until the crust is golden brown and the chicken is cooked through.
In a small bowl, whisk the Dijon mustard and raw honey together until the sauce is smooth and emulsified.
Serve the hot, crispy chicken strips immediately with the honey-mustard sauce for dipping.
