cooked riceI like medium grain white rice for this dish
In your slow cooker, whisk together soy sauce, vinegar, garlic, ginger, and brown sugar. Add jalapeño and chicken, and spoon sauce over chicken to cover. Place lid on slow cooker, and cook on low for 4-5 hours, or until chicken is tender.
About a half hour before serving (I do this when I start the rice), stir cornstarch into cold water with a fork until dissolved, and pour into slow cooker. Gently stir, and continue cooking.
Serve chicken and sauce over rice, and garnish with green onions if desired.
