A native Thai woman made this for a Thai cooking class. This is how she learned to make it from her mother. We tasted the dish and it was great. We did not have Pad Thai sauce with it but she said the store bought type was fine. Vegetables or tofu may be substituted for the chicken. She noted that overcooked noodles do not stir-fry well and do not look good. If using fresh noodles, instead of dried, they will cook in less than 1 minute.
