1. Season beef on all sides with Italian seasoning, salt and pepper. Heat olive oil in a pan till almost smoking and sear beef on all sides. Remove beef and turn heat down slightly. Place beef in slow cooker and then saute both onions and mushrooms in the hot pan, allowing them to gain some color and to sweat but not burn. 2. Place onion and mushrooms in slow cooker with the beef. Sprinkle the onion soup mix over and then add both consomme and beer. Turn slow cooker to high and cook for 2 hours, then turn to low and allow to cook for another 4 hours. Alternatively, keep slow cooker on high for a total of 4 hours or start and keep on low for a total of 8-9 hours. 3. Remove the beef from the slow cooker and thinly slice. Return any scraps to the slow cooker and then pile beef on one side of each roll. Top with Swiss cheese and broil briefly to melt the cheese. Top melted cheese with some mushrooms and onions from the slow cooker, add the top of the roll and serve with the aus jus from the slow cooker. ---------------------------------------------------------------------------
