A quick and delicious twist on the classic Philly cheesesteak using hearty portobello mushrooms as a low-carb vessel, filled with juicy steak, sautéed peppers and onions, and melted provolone cheese.
If steak slices are thick, cook an extra minute per side to keep tender. Avoid overcrowding the pan when cooking steak; cook in batches if needed. Removing mushroom gills prevents bitterness and creates more room for filling. For cheese melting, loosely cover mushrooms with foil or broil briefly for a golden crust. Worcestershire sauce adds umami depth. Let mushrooms rest a couple minutes before serving to redistribute juices.
