Provolone Meatloaf with Mushroom Sauce

Why I Love This Recipe
One of my girlfriends daughters was traveling through on a trip. She was stopping to stay the night. Her daughters loves Meatloaf just not her Mom's so she asked me to make "MeatLoaf". She was extremely thrilled and ended up taking the leftovers home with her. It's a family favorite meal and is great the next day heated up as a Meatloaf Sandwich with Thick Crusted French Bread or Rolls. This is great served with Vidalia Onion Mashed Potatoes.
