Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Trim the woody ends off the asparagus and toss them on the baking sheet with 0.5 tablespoon of olive oil and a pinch of sea salt.
In a shallow bowl, combine the almond flour, dried oregano, garlic powder, lemon zest, sea salt, and black pepper.
Pat the chicken breast dry with a paper towel, then dredge it thoroughly in the almond flour mixture, pressing gently to adhere.
Heat the remaining 1 tablespoon of olive oil in an oven-safe skillet over medium-high heat.
Sear the chicken for 3-4 minutes on one side until a golden-brown crust forms, then flip it over.
Place the skillet and the baking sheet with asparagus into the oven.
Roast for 10-12 minutes until the chicken reaches an internal temperature of 165°F and the asparagus is tender.
Drizzle the fresh lemon juice over the chicken and asparagus before serving hot.
