Step 1

In a large zip-top bag, toss together 1 cup cornstarch, salt and pepper . Add the chicken to the bag, and give it a little shake until lightly coated. Remove the chicken from the bag, shaking off excess cornstarch, and discard the cornstarch mixture.

Step 2

In a large nonstick skillet, heat the oil over medium-high heat. Cook the chicken, about 2 to 3 minutes on both sides, then transfer to the slow cooker.

Step 3

In a medium bowl, whisk together the soy sauce, broth, honey, vinegar, lemon juice, zest, sesame oil, garlic and ginger and pour over the chicken. Cover and cook on low for 3 to 4 hours.

Step 4

About 30 minutes prior to serving, whisk together remaining 1 1/2 tablespoons cornstarch with water in a small bowl and stir into the slow cooker. Turn the heat to high and allow the sauce to cook and thicken up for 20 to 30 minutes.

Step 5

Serve over hot rice, and garnish with sesame seeds and green onions if desired.
