Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Slice the chicken breast into even 1-inch thick strips.
In a medium bowl, whisk together the Greek yogurt, lemon juice, garlic powder, smoked paprika, sea salt, and black pepper.
Add the chicken strips to the yogurt mixture, tossing until every piece is thoroughly coated.
In a separate shallow dish, combine the almond flour and dried oregano.
Dredge each marinated chicken strip in the almond flour mixture, pressing gently so the coating adheres.
Place the strips on the prepared baking sheet and lightly drizzle with olive oil.
Bake for 15-18 minutes, flipping halfway through, until the chicken is cooked through and the coating is golden brown.
While the chicken bakes, steam the broccoli florets for 5 minutes until tender-crisp.
Serve the crispy chicken strips immediately alongside the steamed broccoli.
