Step 1

In a medium bowl, combine the egg, 3 tablespoons cornstarch, salt and pepper. Mix well. Add the chicken and toss until each piece is fully coated. Set aside.

Step 2

In a separate medium bowl, combine the soy sauce, brown sugar, vinegar, orange juice and zest, garlic and 1 tablespoon cornstarch. Whisk until cornstarch has dissolved.

Step 3

Heat the oil in a large skillet over medium-high heat. Add the chicken in a single layer (do this in multiple batches, if needed) and cook for 2 minutes per side, or until browned. Transfer the chicken to a paper towel lined plate and cover.

Step 4

Once all of the chicken is cooked, add it back to the skillet, along with the orange sauce. Cook over medium heat until the chicken pieces are fully cooked through, 5-7 minutes.

Step 5

Serve immediately over white rice. Top with green onions and orange zest.
