Preheat your air fryer to 400°F (200°C).
Slice the chicken breast into even 1-inch thick strips.
In a small bowl, whisk the egg until smooth to create an egg wash.
In a separate shallow dish, combine the almond flour, garlic powder, sea salt, and black pepper.
Dip each chicken strip into the egg wash, then dredge in the almond flour mixture until fully coated.
Toss the broccoli florets with olive oil in a small bowl until lightly coated.
Place the chicken tenders and broccoli in the air fryer basket in a single layer, ensuring they do not overlap.
Air fry for 10-12 minutes, flipping the chicken halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken cooks, whisk together the honey and Dijon mustard in a small ramekin.
Serve the crispy chicken tenders alongside the roasted broccoli with the honey mustard sauce on the side for dipping.
