Preheat oven to 425 degrees F. Line a baking sheet with parchment paper; set aside.
Cut chicken into bite-sized pieces; set aside. Whisk eggs together in a small bowl. In a separate bowl, combine Kodiak Cakes, garlic powder, salt and pepper. Dip each piece of chicken in egg, coat in Kodiak Cakes mixture then place on prepared baking sheet.
Generously spray the tops of chicken pieces with nonstick cooking spray. Bake for 25 minutes, turning and spraying with cooking spray halfway through. Remove from oven and set aside.
While chicken is cooking, heat oil in a large skillet over medium high heat. Add minced garlic and ginger paste and cook for 1 minute. Whisk in sesame oil, hoisin sauce, soy sauce and brown sugar.
In a separate bowl, whisk together water and cornstarch then whisk into skillet. Cook, stirring continuously, until thickened. Toss cooked chicken in sauce and garnish with green onion before serving.
