In a large bowl, whisk together soy sauce, brown sugar, honey, rice vinegar, ginger, garlic, and red pepper flakes (if using). Add the chicken cubes and toss to coat evenly. Marinate for at least 15 minutes, or up to 1 hour in the refrigerator.

Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish. In a skillet over medium heat, sauté the broccoli, carrots, and bell pepper until slightly tender, about 5-7 minutes.
