In a small bowl, whisk together soy sauce, honey, sambal oelek, and arrowroot powder to make the sauce. Set aside.
Heat half a tablespoon of sesame oil in a large sauté pan or wok over medium-high heat.
Once hot, add chicken, minced garlic, and grated ginger. Stir fry for 6-8 minutes until chicken is just cooked through. Remove and set aside on a plate.
Add the remaining sesame oil to the pan, followed by bell peppers, green onions, and broccoli. Sauté for 5 minutes until vegetables are tender yet crisp.
Return the cooked chicken to the pan. Pour the sauce over everything, stirring well to coat.
Cook for an additional 2-3 minutes as the sauce thickens slightly and becomes glossy.
Turn off the heat, allowing the dish to rest for 2-3 minutes.
Serve warm over brown rice, topping with crushed peanuts and extra sambal oelek for heat if desired.
