Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
Crack the egg into a shallow bowl and whisk it thoroughly until the yolk and white are fully combined.
In a separate shallow dish, mix the almond flour, dried oregano, garlic powder, sea salt, and black pepper until well blended.
Dip each chicken tenderloin into the whisked egg, allowing any excess to drip off, then press it into the almond flour mixture to coat all sides.
Arrange the coated chicken tenderloins on the prepared baking sheet and lightly drizzle them with the extra virgin olive oil.
Bake for 15 to 18 minutes, flipping halfway through, until the internal temperature reaches 165°F and the coating is beautifully golden.
While the chicken is in the oven, steam the broccoli florets over boiling water for about 5 minutes until they are bright green and tender-crisp.
Plate the crispy chicken tenderloins alongside the steamed broccoli and warm cooked quinoa for a balanced, clean-eating meal.
