Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into even strips, roughly 1-inch wide, to ensure they cook at the same rate.
In a shallow bowl, whisk the egg thoroughly. In a separate shallow dish, combine the almond flour, garlic powder, smoked paprika, sea salt, and black pepper.
Dip each chicken strip into the whisked egg, allowing excess to drip off, then coat completely in the almond flour mixture, pressing gently so the breading adheres.
Place the breaded chicken strips on one side of the prepared baking sheet. On the other side, spread out the broccoli florets and drizzle them with olive oil.
Bake for 15 to 18 minutes, flipping the chicken tenders halfway through, until the crust is golden-brown and the chicken is cooked through.
While the chicken and broccoli roast, whisk together the Dijon mustard, honey, and Greek yogurt in a small bowl until the sauce is creamy and smooth.
Remove from the oven and serve the crispy tenders immediately alongside the roasted broccoli and the honey mustard dipping sauce.
