Preheat the oven to 400°F and line a baking sheet with parchment paper or lightly coat with cooking spray.
Pat the chicken breast dry and, if desired, pound it to an even thickness for uniform cooking.
Beat the egg white in a small bowl. In another shallow dish, place the almond flour.
Dip the chicken breast first in the egg white, ensuring it's fully coated, and then dredge it in almond flour until evenly covered.
Place the coated chicken on the prepared baking sheet and lightly spray the top with cooking spray.
Bake the chicken for 20-25 minutes or until the internal temperature reaches 165°F, flipping halfway for even crispiness.
While the chicken bakes, prepare the sticky sauce: In a small saucepan over medium-low heat, combine minced garlic, grated ginger, low-sodium soy sauce, honey, and cornstarch. Stir continuously until the mixture begins to thicken slightly, about 2-3 minutes.
Steam the broccoli until tender yet vibrant, about 4-5 minutes.
Once the chicken is cooked, drizzle the sticky garlic ginger sauce generously over the top.
Plate the crispy chicken alongside the steamed broccoli and serve immediately.
