Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a shallow bowl, whisk the egg until smooth. In a separate shallow dish, combine the almond flour, parmesan cheese, dried oregano, garlic powder, sea salt, and black pepper.
Dip each chicken tenderloin into the beaten egg, allowing the excess to drip off, then dredge through the almond flour mixture, pressing firmly so the coating adheres to all sides.
Arrange the coated chicken on the prepared baking sheet and lightly drizzle with the extra virgin olive oil.
Bake for 15 to 18 minutes, flipping the tenderloins halfway through, until the crust is crispy and the chicken is cooked to an internal temperature of 165°F.
While the chicken is baking, steam the broccoli florets over boiling water for 5 to 6 minutes until they are bright green and tender-crisp.
Serve the crispy chicken tenderloins immediately alongside the steamed broccoli.
