This is the answer to the age old question" These pork tenderloins are inexpensive and tender, but what should I do with them?" Borrowed from the beef version of Wellington, this rendering is affordable for all, and gourmet fare for those that don't have the acquired palate for pate'. It is also delicious using beef tenderloin. Pork tenderloins are tender and juicy, but don't have a very bold, meaty flavor. They do, however lend themselves well to mushrooms and beef flavors. This recipe makes good use of that fact, and couples it with the rich buttery flakiness of puff pastry. If fresh herbs aren't available, they may be replaced with dried ground 1/4tsp of each of the herbs.
