Preheat your oven to 400°F and lightly grease a baking sheet with the olive oil.
Slice the chicken breast into even strips.
In a shallow bowl, whisk the egg until smooth. In a separate shallow bowl, combine the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken strip into the egg wash, then dredge in the almond flour mixture until fully coated.
Arrange the chicken strips 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, whisk together the honey, Dijon mustard, and apple cider vinegar in a small bowl to create the dipping sauce.
Steam the broccoli florets for 4-5 minutes until they are tender-crisp and bright green.
Serve the hot chicken strips immediately with the honey mustard sauce and steamed broccoli on the side.
