Slice the chicken breast into even strips and place them in a bowl with the buttermilk to marinate for 15 minutes.
In a shallow dish, whisk together the whole wheat flour, smoked paprika, 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 flour mixture until coated.
Heat the avocado oil in a large non-stick skillet over medium-high heat.
Place the chicken in the skillet and cook for 4-5 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
While the chicken cooks, whisk the Dijon mustard, raw honey, and apple cider vinegar together in a small bowl to create the sauce.
In a separate bowl, toss the shredded cabbage with lemon juice and a pinch of salt to create a fresh slaw.
Serve the crispy chicken strips alongside the cabbage slaw and drizzle with the honey-mustard sauce.
