Fillet of Pork with Prune Sauce Recipe

Preheat oven to 350F.
Brown pork in olive oil in a heavy skillet over medium-high heat. Remove pork. Sauti green onions and prunes, add sake, prune juice, red wine vinegar and teriyaki sauce. Cook until bubbly. Add the cornstarch and water mixture and the hot mustard. Continue cooking until thick, about 1-2 minutes.
Put a layer of pork in the bottom of a 9x12-inch casserole dish. Season meat with garlic powder. Pour 1/2 of the prune sauce over first layer of pork. Repeat with a second layer of pork. Pour remaining sauce over meat and cover. Bake for 1 hour and 15 minutes. Let sit for 15 minutes before serving.
Serve this dish over long grain rice and garnish with chopped green onions.
