Preheat oven to 400 degrees. Heat 1 tablespoon of the oil in a saute pan, add the onions, celery, peppers, green onions, shallots, and garlic, and saute for 1 minute. Stir in the by leaves and Essence and saute for 2 minutes. Add the oysters, their liquor, and the water, Worcestershire sauce, and hot sauce, saute for 1 minute. Remove from the heat. Turn into a bowl, add the bread crumbs, and mix thoroughly incorporated. Season with salt and pepper.
Make a vertical incision in the side edge of each filet with a small sharp knife, and open up a pocket about three-quarters of the way into the meat. Sprinkle the remaining Essence all over the steaks. Stuff each steak with 1/4 cup of the oyster stuffing.
Heat the remaining 1 tablespoon oil in a large ovenproof skillet over high heat. When the oil is hot, add the filets and sear on both sides , about 3 minutes on each side. Finish the filets in the oven for about 5 minutes for medium rare. Place the potatoes plate with the filet on top. Spoon the sauce over the top and garnish with the fried oysters and green onions.
