Combine the sauce ingredients together in a medium saucepan. Measure out 3 tablespoons and add to a large mixing bowl. Set aside the saucepan. To the mixing bowl, lightly beat in the egg white and add chicken pieces. Mix well. In a large zip-top freezer bag, combine the cornstarch, panko crumbs, salt and black pepper. Add the chicken and shake well to coat.

For the baked version: Preheat oven to 375F. Place chicken in a single layer on a large baking sheet lined with parchment paper. Bake for 15 minutes or until chicken is cooked, flipping once in between. Turn oven to broil for 2-3 minutes or until chicken pieces turn light brown on top and crisp up. Watch your chicken closely so it doesn't burn. Remove chicken from oven and toss together with heated lemon sauce, coating well. Garnish with green onions, sesame seeds and serve immediately with rice or noodles, if desired.
