For the casserole:

• Boneless, skinless chicken breasts
• Cooked brown or white rice

directions

1. Make the sauce: In a saucepan, combine soy sauce, water, brown sugar, ginger, and garlic. Bring to a boil, then stir in a cornstarch slurry (cornstarch mixed with water). Cook until thickened, then set aside.
2. Assemble the base: Preheat oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish. Place raw chicken breasts in the dish and pour about 1 cup of teriyaki sauce over them.
3. Add veggies: Arrange the steamed vegetables around the chicken. Cover the dish tightly with foil and bake for 30 minutes, or until the chicken is fully cooked (internal temp 165°F).
4. Shred and combine: Remove from the oven, shred the chicken in the dish using two forks. Add cooked rice and most of the remaining sauce. Mix gently until well combined.
5. Final bake: Bake uncovered for another 10 minutes to heat everything through and allow flavors to meld.
6. Serve: Let rest for 5 minutes. Drizzle with remaining sauce and garnish with green onions or sesame seeds if desired.
