Preheat your air fryer to 400°F (200°C).
Cut the chicken breast into 1-inch bite-sized pieces and pat them dry with a paper towel to ensure maximum crispiness.
In a medium bowl, whisk together the almond flour, arrowroot starch, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Toss the chicken pieces in the flour mixture until each piece is thoroughly and evenly coated.
Lightly coat the air fryer basket with avocado oil and arrange the chicken in a single layer, ensuring they are not touching.
Air fry for 10-12 minutes, flipping halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken cooks, whisk together the Greek yogurt, Dijon mustard, lemon juice, and honey in a small ramekin to create the dip.
Steam the broccoli florets for 4-5 minutes until they are tender and bright green.
Serve the crispy chicken bites immediately with the zesty yogurt dip and steamed broccoli on the side.
