Preheat your oven to 425°F and line a large baking sheet with parchment paper to ensure easy cleanup.
Slice the sweet potato into 1/2-inch thick fries and toss them in a bowl with half of the olive oil, sea salt, and black pepper.
Cut the chicken breast into even strips to ensure they cook at the same rate as the fries.
Whisk the egg white in a small bowl until frothy, and in a separate shallow dish, combine the almond flour, garlic powder, and oregano.
Dip each chicken strip into the egg white, then dredge through the almond flour mixture until thoroughly coated.
Arrange the sweet potato fries and chicken strips on the prepared baking sheet in a single layer, drizzling the remaining oil over the chicken.
Bake for 22 minutes, flipping both the fries and chicken halfway through, until the chicken is golden and the fries are perfectly tender.
