Heat oven to 375 degrees F. Line a baking sheet with a nonstick mat or foil and lightly spray with cooking spray. Place baking sheet in the oven to heat up.
Meanwhile, whisk the Breading flour, salt and pepper together in a freezer bag. Whisk eggs together in a separate freezer bag or shallow bowl.
Add chicken to eggs and turn/stir to coat. Working in batches, remove coated chicken from bag, dabbing off excess egg wash with paper towels then add chicken to Breading bag. Seal bag and toss until chicken is evenly coated.
Carefully place chicken on the hot baking sheet in an even layer and spray generously with cooking spray. Bake at 375 degrees for 10 minutes then move the baking sheet about 8" away from broiler and broil until crispy, watching closely so the chicken doesn't burn (about 2-4 minutes). Flip chicken pieces over and broil another 2-3 minutes, or until crispy.
While the chicken is baking, make the Orange Sauce. Whisk all of the Orange Sauce ingredients together in a medium saucepan. Bring to a boil, stirring constantly then reduce to a simmer until thickened, stirring occasionally. Remove from heat.
Add baked chicken to a large bowl then pour sauce over chicken. Stir until evenly coated. Serve over rice and garnish with green onions if desired.
