Roasted pork tenderloin is surrounded with tender vegetables in this easy one dish meal. This type of meal is especially easy to put together on a weeknight since it only uses five ingredients, and all you need to add is a nice green salad and perhaps some breadsticks or rolls made with refrigerated dough. Make sure you are buying a pork tenderloin for this recipe, not a pork loin roast. The tenderloin is much smaller and cooks in a shorter period of time. The label should state, quite clearly "Tenderloin of pork". If you're not sure, ask the butcher.
