Restaurant-Style Salisbury Steak Burgers with Swiss Cheese Smothered in Cremini Mushroom & Caramelized Onion Gravy
  What do you make when you're torn between wanting a good old-fashioned home-cooked comfort meal, and wanting a summertime burger?  Combine the two into one!  I just didn't want to do the whole meatloaf, mashed potatoes, gravy, veggie, biscuit thing, you know? It was disgustingly hot and humid, and I had the A/C off.
