Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper for easy cleanup.
Cut the chicken breast into 1-inch bite-sized pieces, ensuring they are uniform in size for even cooking.
In a shallow bowl, whisk the egg until smooth. In a separate shallow bowl, whisk together the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Dip each piece of chicken into the egg wash, then dredge through the almond flour mixture, pressing gently so the coating adheres to all sides.
Arrange the coated nuggets on the prepared baking sheet and lightly drizzle or spray with the extra virgin olive oil.
Bake for 15 to 18 minutes, flipping halfway through, until the nuggets are golden brown and reach an internal temperature of 165°F.
While the chicken is baking, whisk together the raw honey, Dijon mustard, and apple cider vinegar in a small ramekin to create the dipping sauce.
Steam the broccoli florets for 4 to 5 minutes until they are bright green and tender-crisp.
Serve the hot chicken nuggets alongside the honey mustard sauce and the steamed broccoli.
