Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Peel the sweet potato and slice it into 1/2-inch thick fries, ensuring they are uniform in size for even cooking.
Place the sweet potato fries on one side of the baking sheet, drizzle with the olive oil, and toss with a small pinch of the sea salt and black pepper.
Slice the chicken breast into even 1-inch thick strips or tenders.
In a shallow bowl, whisk the egg until smooth. In a separate shallow bowl, combine the almond flour, garlic powder, onion powder, smoked paprika, dried oregano, and the remaining salt and pepper.
Dip each chicken strip into the egg wash, letting any excess drip off, then dredge thoroughly in the almond flour seasoning mixture until well coated.
Arrange the coated chicken tenders on the other side of the baking sheet, leaving space between each piece for air circulation.
Bake for 20-25 minutes, flipping the chicken and tossing the fries halfway through, until the chicken is golden and cooked through and the fries are tender.
Remove from the oven and let the chicken rest for 2 minutes before serving to maintain juiciness.
