Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Cut the chicken breast into 1-inch bite-sized pieces and pat them thoroughly dry with a paper towel.
In a small shallow bowl, whisk the egg until smooth. In a second shallow bowl, combine the almond flour, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken piece into the egg wash, allowing any excess to drip off, then dredge in the almond flour mixture until evenly coated.
Place the coated chicken bites onto the prepared baking sheet and lightly drizzle or spray with the olive oil.
Arrange the broccoli florets on the other side of the same baking sheet, seasoning them with a tiny pinch of salt.
Bake for 15 to 18 minutes, flipping the chicken halfway through, until the coating is golden-brown and the chicken is cooked through.
While the chicken bakes, whisk together the Dijon mustard and raw honey in a small ramekin to create the dipping sauce.
Serve the warm chicken bites immediately alongside the roasted broccoli and the honey mustard sauce.
