Preheat oven to 400°F and line a baking sheet with parchment paper.
In a shallow bowl, whisk the egg white until slightly frothy.
In a separate bowl, combine almond flour, nutritional yeast, garlic powder, smoked paprika, salt, and pepper.
Dip each chicken tenderloin into the egg white, then dredge in the almond flour mixture until evenly coated.
Place chicken on the prepared baking sheet and bake for 15-18 minutes until golden and cooked through.
While chicken bakes, steam the broccoli florets until tender-crisp.
In a small ramekin, whisk together Dijon mustard, honey, and apple cider vinegar for the dipping sauce.
Serve the crispy chicken alongside the steamed broccoli with the honey-mustard sauce on the side.
