Preheat your oven to 400°F and line a large baking sheet with parchment paper.
Slice the chicken breast into even, thin strips to ensure they cook quickly and remain juicy.
In a shallow bowl, whisk the egg until smooth to create a binder for the coating.
In a separate shallow dish, combine the almond flour, nutritional yeast, garlic powder, onion powder, sea salt, and black pepper.
Dip each chicken strip into the whisked egg, then dredge in the almond flour mixture until thoroughly and evenly coated.
Place the coated chicken tenders and the broccoli florets onto the prepared baking sheet, drizzling the broccoli and chicken with olive oil.
Bake for 15-18 minutes, flipping the chicken halfway through, until the coating is golden and the chicken is cooked through.
In a small bowl, whisk together the Dijon mustard and honey until smooth to create the dipping sauce and serve alongside the warm tenders.
