This sweet and sour chicken stir-fry is made with lean chicken breast, colorful vegetables, and served with brown rice for added fiber and nutrients. The chicken is cooked in a tangy sauce made with vinegar, ketchup, and soy sauce, while the vegetables add crunch and freshness. The brown rice provides a healthier alternative to white rice, as it is higher in fiber and has a lower glycemic index. This dish is a balanced and nutritious meal that is perfect for a quick and easy weeknight dinner.
