Preheat your oven to 400°F and line a large baking sheet with parchment paper for easy cleanup.
In a shallow bowl, whisk the egg until smooth; in a separate shallow dish, combine the almond flour, garlic powder, onion powder, smoked paprika, sea salt, and black pepper.
Dip each chicken tender into the egg wash, allowing the excess to drip off, then roll in the almond flour mixture, pressing firmly so the coating adheres.
Arrange the coated tenders on the prepared baking sheet and bake for 15 to 18 minutes, flipping halfway through, until the crust is golden and the chicken is cooked through.
While the chicken is in the oven, whisk together the Dijon mustard, raw honey, and apple cider vinegar in a small bowl to create the dipping sauce.
Steam the broccoli florets in a steamer basket over boiling water for 5 minutes until tender-crisp and bright green.
Serve the hot, crispy chicken tenders immediately with the honey mustard sauce and the steamed broccoli on the side.
