- Stir together teriyaki sauce, cane sugar, sesame oil, ginger and garlic in a saucepan over medium-low heat. Once sauce is boiling, reduce heat to low and simmer for 15 minutes or until sauce has reduced slightly and sugar is completely dissolved. Pour sauce into a small bowl to cool for 10 minutes.
- Preheat oven to 400ºF and line a medium baking pan with parchment paper. Place pieces of chicken on the bottom half of sheet pan and drizzle with ¼ cup of sauce. Use hands to coat chicken with sauce. Bake for 15 minutes.
- While chicken bakes, stir together brown rice, carrots, peas and ¼ cup of sauce in a small bowl. Carefully remove baking pan from oven and use a spatula to stir chicken. Spread rice mixture on the other half of pan. Return to oven for 12-15 minutes longer or until chicken is cooked through and rice is lightly crisped.
- Remove pan from oven. Drizzle with remaining sauce and garnish with green onion, cilantro and sesame seeds. Serve hot. Freeze leftovers in an airtight container.
