This is a quicker and easier recipe for chop suey since frozen stir-fry vegetables and a chop suey mix are used. I just added a half-lb cooked shrimp. Below are the only ingredients you need. The mix has been added already to the soy sauce and water mixture. A cooking oil was also added to fry again the shrimp for a few seconds and the vegetables were added. The mixture was added when the vegetables were crisp-tender, when simmered in about 7 minutes, medium heat. You may add black pepper if desired.
