Lemon and capers add bright, briny flavor that takes this easy pork tenderloin stir-fry to the next level—and it’s ready in just 30 minutes. Pork tenderloin is more expensive than pork loin, but it's the most tender cut for stir-frying. Be sure to have all of your ingredients ready to go before you start since stir-frying is a quick, nonstop cooking process. Additionally, the pork and vegetables should be cut into pieces that are a similar size so they cook quickly and evenly. The reason for adding the lemon juice after the finished dish has been transferred to the serving bowl(s) is that the acid in lemon juice would strip the patina from the wok if it sat for more than a minute.
