Here's what you'll need. Butter not pictured. Definitely use the packet gravy. It carries that same salt flavor as it does in Oklahoma.
Add your butter, mushrooms, thick sliced Spanish onions, a dash of fresh ground black pepper and granulated garlic to pan.
Season your formed patties top and bottom.
This is the very best pre-fabed brand out there. Just microwave.
Add your beef stock and water. Bring to a steady boil. Add your powdered gravy. Whisk constantly until gravy is thickened. Add less water if you want a thicker gravy.
When your onions are almost translucent - add your patties.
Fry onion until fully translucent.
Finish frying your patties until medium rare.
Set aside and toast your bread.
Place 1 slice toasted bread down and add mashed potatoes. Add onion mixture and gravy. Add another layer of potatoes and onions with more gravy. Set second toasted slice to the side of sandwich. Enjoy!
