In a large zip-close bag, combine lemon juice, soy sauce, sesame oil, garlic, and ginger.
Add in the chicken and vegetables, seal the bag, and use hands to move the ingredients around in the bag until all of the chicken and vegetables are coated with the lemon sesame dressing.
Refrigerate for at least one hour. Cook ingredients in a large skillet set to medium heat, approximately 15 minutes, or until the chicken is fully cooked. Drain the juices from the stir fry.
