Spray the inside of a slow cooker with nonstick cooking spray. Season the chicken with salt and pepper to taste. Place the meat in a large zip-top bag or a large bowl. Add the cornstarch to the bag, seal, and toss to coat the chicken pieces. Place the chicken in the bottom of the prepared slow cooker.
In a medium bowl, whisk together the orange marmalade, soy sauce, sesame oil, orange zest, garlic, and ginger.
½ cup orange marmalade, ¼ cup less-sodium soy sauce, 2 tablespoons sesame oil, 2 teaspoons minced garlic, 1 teaspoon minced or grated fresh ginger
Pour the sauce over the chicken. Stir gently to make sure that all of the chicken pieces are coated in sauce.
Cover slow cooker and cook on LOW for 3-4 hours (or on HIGH for 1 - 2 hours). Keep an eye on it, though. Some slow cookers may be done in as little as 2 hours on LOW. During the final 15 minutes of cooking, add the broccoli to the slow cooker.
1 (16 ounce) package frozen broccoli florets,
When the broccoli is crisp-tender, give everything a good stir. If the sauce looks too thick at this point, add water or orange juice to thin until it reaches the desired consistency. Spoon the chicken, broccoli, and sauce over rice. Garnish with sliced green onions or sesame seeds, if desired.
