Preheat your oven to 400°F and lightly grease a rimmed baking sheet with one teaspoon of the olive oil.
Place the chicken breast in a shallow bowl and pour the buttermilk over it, letting it soak for 10 minutes to tenderize.
In a separate shallow dish, whisk together the almond flour, half of the smoked paprika, garlic powder, sea salt, and black pepper.
Remove the chicken from the buttermilk, dredging it thoroughly in the almond flour mixture until evenly coated on all sides.
Place the chicken on the prepared baking sheet and bake for 18-22 minutes until the crust is golden and the internal temperature reaches 165°F.
While the chicken cooks, heat the remaining teaspoon of olive oil in a large skillet over medium heat.
Add the minced garlic to the skillet and sauté for 30 seconds until fragrant, then add the chopped collard greens and a splash of water.
Cover the skillet and steam the greens for 5 minutes until tender, then stir in the apple cider vinegar and the remaining smoked paprika.
Plate the crispy chicken alongside the smoky collard greens and enjoy immediately while hot.
