  1. In a large skillet add the beef on medium high heat and cook well, breaking it apart but leaving some chunks about the size of a raspberry or small grape (don't crush the heck out of it, the larger crumbles will help give the sandwich stability).

  2. Cook until well browned (5-6 minutes), then remove from the pan.

  3. Add 1 tablespoon of butter along with the sliced mushrooms and cook for 2-3 minutes on medium high heat until they're browned, then remove them from the pan.

  4. Add in the remaining butter, diced mushrooms, onions and garlic to the pan and cook for 2-3 minutes on medium high heat until they're browned.

  5. In a large measuring cup whisk together the Worcestershire sauce, sour cream, beef broth and cornstarch before adding it to the pan along with the cooked beef and stirring well.
  6. Continue cooking until the sauce starts to evaporate and the mixture becomes "sloppy" (about 5-6 minutes).

  7. The consistency you are looking for is reduced enough that spoonfuls can be placed on top of each other with the bottom spoonful not spreading more than a half inch or so.
  8. Toast the buns then spoon over the mixture and top with sour cream, sliced cooked mushrooms and mozzarella cheese.
