Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Slice the chicken breast into even strips. In a small bowl, whisk the egg until smooth.
In a separate shallow dish, combine the almond flour, garlic powder, onion powder, smoked paprika, half of the sea salt, and half of the black pepper.
Dip each chicken strip into the whisked egg, then dredge thoroughly in the almond flour mixture until fully coated, and place on one side of the baking sheet.
Place the broccoli florets on the other side of the baking sheet, drizzle with olive oil, and season with the remaining sea salt and black pepper.
Bake for 15 to 18 minutes, flipping the chicken tenders halfway through, until the coating is golden brown and the chicken is cooked through.
While the chicken bakes, whisk together the Dijon mustard, honey, and avocado oil mayonnaise in a small ramekin until smooth.
Serve the crispy chicken tenders immediately alongside the roasted broccoli and honey mustard dipping sauce.
