Preheat your oven to 400°F (200°C).
In a mixing bowl, combine the cubed chicken with the flour, orange zest, and black pepper.
In a separate bowl, whisk together the fresh orange juice, tamari or soy sauce, rice vinegar, honey, grated garlic, grated ginger, chili paste, and toasted sesame oil.
Add the sauce to the chicken in the mixing bowl and stir until the chicken is well-coated. Let it marinate for about 10 minutes if you have time.
Wash the broccoli florets and set them aside.
Spread the marinated chicken evenly on a large sheet pan. Scatter the broccoli florets around the chicken. Drizzle everything with extra virgin olive oil.
Bake for about 20-25 minutes, or until the chicken is cooked through and the broccoli is tender but still vibrant. Stir halfway through to ensure even cooking.
Remove from oven and serve garnished with sliced green onions and sesame seeds. Enjoy over rice or quinoa if desired.
