Pre-heat the oven to 350.
Combine the soy sauce, the ½ cup water, the brown sugar, honey, ginger, olive oil and garlic in a small saucepan and cover. Bring to a boil over medium heat. Remove lid and cook for one minute once boiling.
While waiting for the sauce to come to a boil, stir together the corn starch and 2 tablespoons of water in a separate dish until smooth to form a slurry. Once the sauce is boiling, add the slurry to the saucepan and stir in to combine. Cook for another minute until the sauce starts to thicken and then remove from heat.
Lay the raw chicken breasts flat in a 9x13 casserole dish and pour about a cup of the sauce over top of the chicken. Place the chicken in the oven and cook for 30-35 minutes until breasts are cooked through*. Remove the dish from the oven and shred the chicken right in the dish using two forks.
*While the chicken is cooking, steam or cook your frozen vegetables according to package directions.
When the chicken is shredded and the vegetables are cooked, add the vegetables, pineapple and rice to the casserole dish with the chicken. Add most of the remaining sauce, reserving a bit to drizzle over the top when finished. Stir everything together in the casserole dish until well combined. Return the dish to the oven and cook for 15 minutes. Remove from the oven, drizzle with the remaining sauce and serve.
