If you have a taste for blue cheese you have to try the following"
1. prepare a 6 inch full tenderloin making sure the sinew is removed from sides.
2. carefully sliced down the full length of the tenderloin creating an even pocket its full length.
3. sprinkle crumbled blue cheese the entire lenght of the pocket and then either wrap with string or stitch with long wooden skewer.
4. lightly salt both sides and cover with ground pepper, again light coating.
5. squirt some low sodium soy sauce on bottom of dish and dredge both sides and place in refrigerator until you are ready.
Cook over the stove after placing virgin olive in pan. Make sure it is hot as you want to sear both sides quickly. Keep turning until brown on the outside and med rare in center. If you can get away with medium rare all the better. The blue cheese will gradually melt.
6. take out of pan and remove skewer or string and slice into 1/2 slices through the whole loin.
Let me know how you like it. Enjoy.
