Preheat oven to 375 degrees.

Place the pork loin on a long strip of plastic wrap. Cut the pork loin horizontally stopping at about ½-inch.

Lay the meat open. Sprinkle with salt, pepper, garlic powder, oregano and dried thyme.

In a small bowl, mix together mushrooms, spinach, scallions and ¼ cup stock. Spoon over meat. Sprinkle with feta cheese.

Using plastic wrap to help, roll the meat up into a tight roll. Wrap the pork roll in bacon and tie with kitchen twine. Place on a greased baking sheet and bake for approximately 1-1/2 hrs.

Serve immediately.
