These garlic and orange-flavored pork tenderloin medallions are easy to prepare and they are ready in less than 30 minutes. Orange juice, garlic, and green onions get together to make up the tasty glaze for these pork tenderloin medallions. The pork is browned and then baked to perfection with the flavorful orange and garlic glaze. Pork tenderloin is a lean, mild cut, and it cooks quickly. It becomes dry if cooked too long, so check the meat after it's been in the oven for about 15 minutes. If the medallions are thin, it may take less time.
