Preheat your oven to 400°F (200°C) and line a large rimmed baking sheet with parchment paper.
Place the broccoli florets on the baking sheet and drizzle with 0.5 tbsp of olive oil, half of the sea salt, and half of the black pepper.
Toss the broccoli to coat evenly and roast in the oven for 18-20 minutes until the edges are golden and tender.
While the broccoli is roasting, prepare the chicken coating by mixing the almond flour, dried oregano, garlic powder, and lemon zest in a shallow dish.
Pat the chicken breast dry with a paper towel and season with the remaining sea salt and black pepper.
Dredge the chicken in the almond flour mixture, pressing firmly so the herbs and flour adhere to both sides.
Heat the remaining 0.5 tbsp of olive oil in a non-stick skillet over medium heat.
Add the chicken to the skillet and cook for 6-7 minutes per side, or until the internal temperature reaches 165°F and the crust is golden brown.
Remove the chicken from the heat and let it rest for 3 minutes before slicing.
Plate the herb-crusted chicken alongside the roasted broccoli and serve immediately.
