Preheat the oven to 400°F and line a large baking sheet with parchment paper.
In a shallow bowl, whisk the egg white until it becomes light and slightly frothy.
In a separate shallow dish, combine the almond flour, garlic powder, onion powder, sea salt, and black pepper, mixing well.
Dip each chicken tender into the egg white, then press into the almond flour mixture until thoroughly and evenly coated.
Arrange the coated tenders on the prepared baking sheet and bake for 15-18 minutes, flipping halfway through, until golden and cooked through.
While the chicken is baking, whisk together the honey, Dijon mustard, and Greek yogurt in a small bowl until the sauce is smooth.
Steam the broccoli florets in a steamer basket over boiling water for 4-5 minutes until they are tender and bright green.
Serve the hot chicken tenders immediately with the creamy honey mustard dipping sauce and steamed broccoli on the side.
