Step 1: Preheat Your Oven - Begin by preheating your oven to 425°F (220°C). This high temperature will help to achieve that perfect caramelization on the chicken and veggies.
Step 2: Prepare the Marinade - In a mixing bowl, whisk together the olive oil, reduced sodium soy sauce, chili garlic sauce, fish sauce, orange zest, orange juice, ground ginger, salt, and pepper.
Step 3: Marinate the Chicken - Add the diced chicken breast to the marinade. Toss until the chicken is well-coated. Let it marinate for at least 15 minutes.
Step 4: Chop Your Vegetables - While the chicken is marinating, prepare the vegetables. Wash and chop the broccoli florets, slice the carrots, and cut the red onion into wedges.
Step 5: Combine Chicken and Vegetables - Once the chicken has marinated, add it to the bowl with the vegetables. Toss everything together until the veggies are coated with the marinade.
Step 6: Arrange on the Baking Sheet - Spread the chicken and vegetable mixture evenly on a large baking sheet.
Step 7: Roast in the Oven - Place the baking sheet in the preheated oven and roast for about 20-25 minutes, or until the chicken is cooked through and the vegetables are tender but still crisp.
Step 8: Garnish and Serve - Once out of the oven, let it cool for a couple of minutes. Garnish with fresh orange slices and cilantro if desired.
