To cook rice: Add ¾ cup brown Basmati rice and 1½ cups cold water to a medium-sized pot. Bring to a boil. Turn heat down to low, cover, and simmer for about 40 minutes until water is absorbed and rice is cooked. If using another type of rice, cook according to package directions.
In the meantime, prep all vegetables and make the sauce. Set aside.
To cook orange chicken: Place chicken pieces in bowl. In another small bowl, mix together egg white, salt, and pepper. In another small shallow bowl, add flour.
Dip all chicken pieces into egg mixture and lightly coat with flour. Add to a plate.
Coat a large nonstick pan with cooking spray. Heat 1 teaspoon of oil. Add chicken pieces and cook over medium-high heat for 3 minutes. Coat chicken with cooking spray and using a fork, turn over. Cook an additional 3-4 minutes until golden brown and cooked through. Remove chicken to a clean plate.
Coat same pan again with cooking spray and heat another 1 teaspoon oil. Add garlic and veggies and stir fry about 2 minutes, until softened. Add back chicken and pour in sauce. Heat over medium heat for a few minutes until chicken is hot. Stir often.
Serve over ½ cup rice, if desired.
