Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
In a shallow bowl, combine the almond flour with a pinch of salt and pepper (optional). In another bowl, lightly whisk the egg white.
Dip the chicken breast into the egg white, then dredge it in the almond flour mixture, ensuring an even coating.
Place the coated chicken breast on the prepared baking sheet. Bake in the preheated oven for 20-25 minutes or until the chicken is cooked through and the coating is crispy.
While the chicken is baking, prepare the spicy-sweet sauce. In a small bowl, finely mince the garlic and ginger, then mix with honey and soy sauce. Adjust the seasoning if needed.
For the sauce, you can heat it gently in a small saucepan over low heat for 2-3 minutes to meld the flavors, being careful not to overcook.
Steam the broccoli until tender, about 5-7 minutes.
Once the chicken is almost done, drizzle the warmed garlic-ginger sauce over it, and return to the oven for an additional 3-5 minutes to let the flavors infuse.
Plate the crispy baked chicken alongside the steamed broccoli and serve immediately.
