Make sauce by combining orange juice, Truvia, vinegar, soy sauce, ginger, garlic powder and red pepper flakes in a saucepan over medium-high heat. Whisk continuously for 3-5 minutes.

Heat oil in a large pot over medium-high heat (until around 350 degrees F). Cut chicken into bite-sized pieces and season with salt and pepper; set aside.

Combine Kodiak Cakes and cornstarch in a shallow bowl or dish. In a separate dish, whisk together eggs and egg white.

Dip chicken pieces in egg mixture, then Kodiak Cakes mixture. Working in batches, cook several pieces of chicken at a time in hot oil. Cook for 2-3 minutes, turning halfway through, until golden brown and cooked through. Carefully remove chicken from oil and place on a plate lined with paper towel and repeat until all chicken is cooked.

Toss cooked chicken in sauce before serving, heat through if needed, and garnish with green onion.
