This sweet and hot Chinese dinner tastes as if it came straight out of the wok, but it's fresh from the freezer.
Place cornstarch in a medium bowl. Gradually whisk in orange juice until smooth. Whisk in soy sauce, vinegar, honey, garlic, and red-pepper flakes; season with salt. Set mixture aside.
In a 5-quart nonstick Dutch oven or pot, heat oil over medium-high. Working in batches, cook chicken on one side until slightly browned, 2 to 4 minutes; transfer to a plate, and set aside (chicken will cook more later).
Add broccoli, carrots, and 1/2 cup water to pot. Cook, partially covered, until water has evaporated and broccoli is bright green, 3 minutes. Add reserved chicken and cornstarch mixture; bring to a boil. Cook until chicken is opaque throughout and sauce has thickened, 2 to 3 minutes. Serve stir-fry over rice.
For better health, have more vegetables and lean white-meat chicken and less white rice.
