Preheat your oven to 425°F.
In a bowl, whisk the egg white, then add the cornstarch and a pinch of salt and pepper to create a light coating mixture.
Cut the chicken breast into bite-sized pieces and toss them in the egg white mixture ensuring all pieces are evenly coated.
In a separate small saucepan, combine the fresh orange juice, honey, minced garlic, and grated ginger. Simmer over medium heat until slightly reduced, about 3-4 minutes, then remove from heat.
Pat a baking sheet dry and spread out the broccoli florets. Drizzle with olive oil and season with salt and pepper.
Place the coated chicken pieces on a separate baking tray lined with parchment paper.
Roast the broccoli in the oven for 15 minutes, stirring halfway through, while placing the chicken in the oven concurrently for about 12-15 minutes or until the chicken is fully cooked and slightly crispy.
Once both are cooked, toss the chicken pieces in the orange glaze.
Serve the crispy orange chicken alongside the roasted broccoli and enjoy your balanced, flavorful meal.
