Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into even, finger-sized strips.
In a small shallow bowl, whisk the egg until smooth.
In a separate shallow bowl, combine the almond flour, garlic powder, sea salt, and black pepper.
Dip each chicken strip into the egg wash, allowing excess to drip off, then dredge in the almond flour mixture until evenly coated.
Arrange the chicken on the prepared baking sheet and bake for 15-18 minutes, flipping halfway through, until the coating is golden and the chicken is cooked through.
While the chicken is baking, place the green beans in a steamer basket over boiling water and steam for 5-7 minutes until tender-crisp and bright green.
Toss the steamed green beans with the olive oil and a final pinch of sea salt.
Serve the hot chicken tenders alongside the seasoned green beans for a clean, protein-packed dinner.
